General Description
ADC16R02 realized resistive ladder architecture. part operates from single supply. This designed continuous mode. After signal asserted high, conversion begins. Each conversion takes most clock-cycles. input clock corresponds 28.4 conversion rate. After conversion completed rising edge valid signal used latch bits output. This valid signal also used sample input start next conversion immediately. time goes low, chip will stay reset. ADC16R02 operates power typically less than 2mW. This characteristic makes ADC16R02 ideal application low-power portable devices.

Product Highlights
Low-power operation, less than Hybrid design both resistor network capacitor network guarantees highest accuracy. Offset compensated internally. Single-supply operation. This part operates from single supply. Small layout area, without pads. Conversion rate 28.4 power consumption less than Part realized AMI's 0.6µ process. version AMI's 1.5µ process allows operation higher voltages.
Note: VIN: Input analog voltage. RESET: Reset chip. Active low. CLK: Clock input max). Logic supply voltage Typical). Digital ground (0V). Analog supply voltage Typical). AGND: Analog ground (0V). VREF: Reference Voltage (typically 2.5V). Valid: Valid signal, active high. Indicates conversion complete data latched outputs. Q0-Q15: latched-output ADC. MSB. LSB.
