M62301SP/FP 10 to 12-bit 4-ch Integrating A/D Converter REJ03D0861-0300 Rev.3.00 Mar 25, 2008 Description M62301 semiconductor integrated circuit forms an integrating A/D converter, being connected to a microcomputer unit. By using selection signals and counter clock signals from the unit, a 10 to 12-bit A/D converter can be created at a low cost. The integration time and resolution can be set at the users option by changing external parameters. In addition, the built-in circuit offset, delay time and temperature fluctuation are adjustable, enabling a wide range of applications. M62301 has a 3 input decoder circuit, high-precision reference voltage (1.22 V) generator, current supply and comparator for integration, and voltage-monitoring reset circuit for a 5 V power supply. It is also equipped with girdling to prevent current leak from integration capacitor.

It then selects VREF, obtaining reference pulse TREF. Input is selected next, obtaining input pulse TIN. VIN is obtained by deducting TGND, as the offset, from TREF and TIN. VIN = VREF * TIN - TG TREF - TG By measuring voltage at the maximum input for approximately 500 s under the counter clock of 8 MHz, resolution of approximately 12 bits can be obtained; 500 s 125 ns 212 Note: To ensure discharge from capacitor CI, the decoder input as in the above diagram should stay in mode 1 at least for the period calculated above: Tdi = (CI x VIAmax + 0.49 1 mA ) It is not necessary to measure TGND, and TREF for each channel.

CINT: We suggest that this capacitance be connected to prevent malfunction due to noise. Use CI that leaks as slight current as possible. To prevent leak to the circuit board, we recommend providing guard ring (7), (9). Resolution depends on the number of microcomputer counter clock pulses that are generated while the INT output status is "high" at the maximum input voltage 2.5 V (VCC - 2.5 V). When the microcomputer counter clock frequency is 8 MHz, the resolution can be calculated by using the constant calculated above, as follows; 4700 pF x (2.5 + 0.13) 50 A 1 8M 211 Therefore, the resolution of this system is approximately 11 bits.

CINT: We suggest that this capacitance be connected to prevent malfunction due to noise. Use CI that leaks as slight current as possible. To prevent leak to the circuit board, we recommend providing guard ring (7), (9). Because separate power supplies are provided for the analog are digital sections, the M62301 has two supply voltage VCC and VDD, enabling a wide analog input voltage range VIA. The upper limit of the range is required to be no more than the difference between VCC - 2.5 V as well as VDD, therefore, the analog input voltage range in this application is 0 V to 5 V. When the counter clock frequency is 8 MHz, resolution is; 6800 pF x 1 8M (5 + 0.13) 50 A 212 An A/D converter system with resolution of approximately 12 bits can be formed.
