ADS7869IPZT

ADCs/DACs - Special Purpose Overview

The ADS7869IPZT is an analog motor control front-end integrated circuit manufactured by Texas Instruments. It integrates three simultaneous-sampling, 12-bit analog-to-digital converters (ADCs) capable of a 1 MSPS sampling rate per channel. The device features seven sample-and-hold capacitors to support multi-phase current sensing applications. It operates on a single digital power supply ranging from 2.7 V to 5.5 V and includes an internal reference voltage source. The component is housed in a 100-pin TQFP package with a specified operating temperature range of -40°C to +85°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'IPZT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and pin compatibility. Ensure that the 100-TQFP footprint matches the target PCB design. Confirm RoHS compliance status through the latest production data sheet before finalizing procurement specifications.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring synchronized sampling across multiple phases without external synchronization circuitry. The internal reference simplifies board layout compared to external reference solutions. Verify that the input signal range aligns with the ±VREF specification to ensure accurate 12-bit resolution performance within the linear operating region.

ADCs/DACs - Special Purpose Part Context

The ADS7869 belongs to the ADS7869 family of specialized data converter ICs designed for high-speed motor control applications. It consolidates multiple ADC channels and sample-and-hold circuits into a single package, reducing component count and board space compared to discrete ADC implementations.
