Analog ground. 11MHz bandlimted signal with a 750mV DC offset and a 1V peak to peak full scale amplitude. 44MHz sampling clock. Nominal 1.5V analog reference. ADC conversion results. Unsigned binary output. Vref Input Out[3:0] CK FEATURES 44 MSPS. 4-bit unsigned binary output. Analog supply voltage 3.0V to 3.6V GENERALDESCRIPTION The flash ADC04R01 is intended to oversample an 11MHz bandlimted signal with a 750mV DC offset and a 1V peak to peak amplitude. The conversion range is .25V to 1.25V with 62.5mV steps. A nominal 1.5V external reference and a 44MHz sampling clock are required APPLICATIONS * Fast data acquisition * Instrumentation * DSP control loop * Audio processing 1 (R) ADC04R01 AMERICAN MICROSYSTEMS, INC June, 1998 Preliminary Parameter RESOLUTION DC ACCURACY Differential Linearity Integral Linearity No Missing Codes INITIAL OFFSET ERROR Top of Reference Ladder Bottom of Reference Ladder Offset Drift Coefficient ANALOG INPUT Input Bias Current (latched) Input Bias Current (sampling) Input Resistance Input Capacitance Large Signal Bandwidth Input Slew Rate REFERENCE INPUT Reference Ladder Resistance Reference Input Bandwidth DYNANIC PERFORMANCE Conversion Rate Output Delay (tPD) Transient Response Overvoltage Recovery Time Output Rise Time Output Fall Time ENCODE INPUT Logic "1" Voltage Logic "0" Voltage Logic "1" Current Logic "0" Current Input Capacitance Encode Pulse Width (Low) Encode Pulse Width (High) OVERFLOW INHIBIT INPUT 0 V Input Current AC LINEARITY Effective Number of Bits (ENOB) AMI 0.8 micron CMOS Temp +25C +25C Full Min Typ Max Units Bits LSB LSB LSB LSB LSB LSB uV/C Guaranteed +25C +25C uA uA k Ohm pF Hz V/ms Ohm MHz +25C +25C 44 +25C +25C +25C +25C MSPS ns ns ns ns ns +25C +25C V V mA mA pf ns ns Full mA Bits 2 (R) ADC04R01 AMERICAN MICROSYSTEMS, INC June, 1998 Preliminary Parameter In-Band Harmonics Dc to X.X MHz Dc to X.X MHz Dc to X.X MHz Signal-to-Noise + Distortion (S/(N+D)) Intermodulation Distortion IMD Spurious Free Dynamic Range (SFDR) AMI 0.8 micron CMOS Temp Typ Max 24.5 -37 - -30 5MHz input tone 50 @ 5MHz input tone Total Harmonic Distortion (THD) Parameter POWER SUPPLY Operating Voltage AVDD AVSS VREF Operating Current IADD IDDD Standby Mode POWER CONSUMPTION Operating Mode Standby Mode Min Temp Min Typ 1.5 12 Max Units dB dB dB dB dB dB dB Units Volts Volts V mA mA mA mA mA 3 (R) ADC04R01 AMERICAN MICROSYSTEMS, INC June, 1998 Preliminary AMI 0.8 micron CMOS ABSOLUTE MAXIMUM RATINGS Supply Voltage (-VS) Analog-to-Digital Supply Voltage Differential Analog Input Voltage Digital Input Voltage Reference Input Voltage (+VREF - VREF) Differential Reference Voltage Reference Midpoint Current Digital Output Current Operating Temperature Range Storage Temperature Range Junction Temperature Lead Soldering Temperature (10 sec.)
