ADS7816PB

Analog To Digital Converters (ADC) Overview

The ADS7816PB is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Burr-Brown. It features a high-impedance fully differential analog input and operates with a single 5V supply. The device supports sampling rates up to 200 kSPS while consuming only 1.9 mW of power. It utilizes a 3-wire serial interface compatible with standard microprocessors. Key performance metrics include a maximum throughput of 200 kHz, an input voltage range defined by an external reference, and operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Burr-Brown or Texas Instruments, as TI acquired Burr-Brown's product lines. Confirm the package type corresponds to the PB suffix, typically indicating a plastic small-outline package. Ensure the datasheet matches the specific speed grade and pinout configuration required for the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 12-bit accuracy and low power consumption is required. The differential input is suitable for noise-sensitive applications. Verify that the external reference voltage range aligns with the application's signal requirements, as the ADS7816 requires an external reference.

Analog To Digital Converters (ADC) Part Context

The ADS7816 is part of a family of high-speed, micro-power ADCs that includes the ADS7817 and ADS7822. These devices were engineered for applications requiring fast conversion speeds with minimal power draw. The ADS7816 specifically offers a 200 kSPS sampling rate, distinguishing it from slower variants in the broader ADC market.
