Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIVSX' against the manufacturer's official documentation to confirm package type and temperature grade details. Ensure compatibility with the required digital output driver supply voltage (VDR) range of +1.5V to VD for system interfacing. Confirm that the 48-pin TQFP package dimensions align with the target PCB layout constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel, low-power solution is required for mid-speed signal acquisition. The device is suitable for designs needing flexible output formatting via the OS pin. Consider the 2.5 to 3 clock cycle pipeline latency when designing timing-critical digital interfaces. Ensure the external reference voltage (VREF) is maintained between 0.8V and 1.5V for optimal performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC10D020 family of high-performance, low-power CMOS A/D converters. The series is designed for applications requiring simultaneous sampling of two channels with minimal power dissipation. The device utilizes a unique two-stage architecture to achieve high linearity and speed while maintaining a simple single-supply operation profile.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements should be sought within the ADC10D020 family variants. Verify pinout compatibility for the 48-pin TQFP package if substituting with other TI dual-channel ADCs. Cross-reference specifications such as ENOB, DNL, and power consumption to ensure equivalent performance in the target application.

Analog To Digital Converters (ADC) FAQ

How does the Offset Correct (OC) pin function?

A low-to-high transition on the OC pin initiates an independent offset correction sequence for each converter. This process takes 34 clock cycles, during which 32 conversions are averaged and subtracted from subsequent readings to minimize offset error.

What is the difference between Multiplexed and Parallel output modes?

In Parallel mode (OS pin high), I and Q data are present simultaneously on their respective 10-bit buses. In Multiplexed mode (OS pin low), I and Q data are time-multiplexed onto the I output bus, with the I/Q pin indicating which channel's data is currently valid.

What are the power consumption levels in different modes?

Normal operation consumes typically 150 mW. Standby mode (STBY pin high) reduces consumption to about 27 mW with an 800 ns recovery time. Power-down mode (PD pin high) reduces consumption to less than 1 mW with a recovery time of less than 1 ms.
