LTC1196-1BCS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1196-1BCS8#TRPBF is an 8-bit, 1Msps successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It features a differential analog input and operates on a single supply voltage ranging from 2.7V to 6V. The device dissipates 10mW at 3V and 50mW at 5V during full-speed operation. It utilizes a 3-wire serial interface for data output and supports external voltage references. The B-grade variant guarantees a total unadjusted error of ±1/2 LSB over the commercial temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the #TRPBF suffix indicates tape and reel packaging containing 2500 units per reel. Confirm the -1B designation corresponds to the B-grade performance specifications and the SO-8 plastic package format. Ensure compatibility with the required operating temperature range of 0°C to 70°C for this specific part marking.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1196-1BCS8#TRPBF when a differential input configuration is required for noise rejection or floating signal measurement. Choose this part over the LTC1198 if multiplexing capabilities are unnecessary and a dedicated differential channel is preferred. Ensure the system clock can support up to 14.4MHz for maximum throughput at 5V operation.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1196/LTC1198 family of high-speed, low-power ADCs. The -1 suffix denotes a single-channel differential input architecture, distinguishing it from the -2 suffix which typically implies different pinout or configuration options within the same series. The B grade offers tighter error specifications compared to the A grade.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical specifications against alternative SAR ADCs if sourcing constraints require substitution.
