(R) ADS-946 (R) 14-Bit, 8MHz Sampling A/D Converters PRODUCT OVERVIEW The low-cost ADS-946 is a 14-bit, 8MHz sampling A/D converter. This device accurately samples full-scale input signals up to Nyquist frequencies with no missing codes. Excellent differential nonlinearity error (DNL), signal-to-noise ratio (SNR), and total harmonic distortion (THD) make the ADS-946 the ideal choice for both time-domain (CCD/FPA imaging, scanners, process control) and frequencydomain (radar, telecommunications, spectrum analysis) applications. The functionally complete ADS-946 contains a fast-settling sample-hold amplifier, a subranging (two-pass) A/D converter, an internal reference, FEATURES 14-bit resolution 8MHz guaranteed sampling rate No missing codes over full HI-REL temperature range Ideal for both time and frequency-domain applications Excellent THD (-75dB) and SNR (77dB) Edge-triggered; No pipeline delays Small, 24-pin, ceramic DDIP or SMT Requires only 5V supplies Low-power, 2 Watts MIL-STD-883 screening available timing/control logic, and error-correction circuitry. Digital input and output levels are TTL. The ADS946 only requires the rising edge of a start convert pulse to operate. Requiring only 5V supplies, the ADS-946 typically dissipates just 2 Watts. The device is offered with a bipolar input range of 2V. Models are available for use in either commercial (0 to +70C) or HI-REL (-55 to +125C) operating temperature ranges. A proprietary, auto-calibrating, error-correcting circuit allows the device to achieve specified performance over the full HI-REL temperature range.

All supplies and the clock (start convert pulses) must be present during warmup periods. The device must be continuously converting during this time. Contact DATEL for other input voltage ranges. An 8MHz clock with a 20nsec positive pulse width is used for all production testing. See Timing Diagram, Figure 4, for more details.

The minimum limits are +4.75V and -4.75V when operating at +125C. Full Scale Amplitude Actual Input Amplitude 6.02 TECHNICAL NOTES 1. Obtaining fully specified performance from the ADS-946 requires careful attention to pc card layout and power supply decoupling. The device's analog and digital ground systems are connected to each other internally. For optimal performance, tie all ground pins (14, 19 and 24) directly to a large analog ground plane beneath the package. Bypass all power supplies to ground with 4.7F tantalum capacitors in parallel with 0.1F ceramic capacitors. Locate the bypass capacitors as close to the unit as possible. 2. The ADS-946 achieves its specified accuracies without the need for external calibration. If required, the device's small initial offset and gain errors can be reduced to zero using the adjustment circuitry shown in Figures 2 and 3. When using this circuitry, or any similar offset and gain calibration hardware, make adjustments following warmup. To avoid interaction, always adjust offset before gain. 3. Applying a start convert pulse while a conversion is in progress (EOC = logic 1) will initiate a new and inaccurate conversion cycle. Data for the interrupted and subsequent conversions will be invalid. 4. A passive bandpass filter is used at the input of the A/D for all production testing. 2k: GAIN ADJUST +5V 1.98k: SIGNAL INPUT To Pin 21 of ADS-946 50: -5V Figure 2.

To avoid interaction, offset must be adjusted before gain. The ranges of adjustment for the circuits in Figures 2 and 3 are guaranteed to compensate for the ADS-946's initial accuracy errors and may not be able to compensate for additional system errors. 1. Apply +1.99963V to the ANALOG INPUT (pin 21). 2. Adjust the gain potentiometer until all output bits are 1's and the LSB flickers between 1 and 0. 3. To confirm proper operation of the device, vary the input signal to obtain the output coding listed in Table 2. A/D converters are calibrated by positioning their digital outputs exactly on the transition point between two adjacent digital output codes. This can be accomplished by connecting LED's to the digital outputs and adjusting until certain LED's "flicker" equally between on and off. Other approaches employ digital comparators or microcontrollers to detect when the outputs change from one code to the next. INPUT VOLTAGE RANGE ZERO ADJUST +1/2 LSB GAIN ADJUST +FS -11/2 LSB 2V +122V +1.99963V Offset adjusting for the ADS-946 is normally accomplished at the point where the MSB is a 1 and all other output bits are 0's and the LSB just changes from a 0 to a 1. This digital output transition ideally occurs when the applied analog input is +1/2 LSB (+122V). Table 1.

All room-temperature (TA = +25C) production testing is performed without the use of heat sinks or forced-air cooling. Thermal impedance figures for each device are listed in their respective specification tables. These devices do not normally require heat sinks, however, standard precautionary design and layout procedures should be used to ensure devices do not overheat. The ground and power planes beneath the package, as well as all pcb signal runs to and from the device, should be as heavy as possible to help conduct heat away from the package. Electrically-insulating, thermally-conductive "pads" may be installed underneath the package. Devices should be soldered to boards rather than socketed, and of course, minimal air flow over the surface can greatly help reduce the package temperature. N START CONVERT N+1 20ns typ.

For sampling rates less than 8MHz, the start pulse can be wider than 110nsec, however a minimum pulse width low of 15nsec should be maintained. An 8MHz clock with a 20nsec positive pulse width is used for all production testing. Figure 4.
