Overview
The TLV1570IPWG4 is a 10-bit, 1.25 MSPS (Mega Samples Per Second) analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the TLV1570 series and is designed for high-speed data acquisition applications. It features an 8-channel input multiplexer, a successive approximation register (SAR) ADC, and a high-speed serial interface compatible with SPI and QSPI microcontrollers. The TLV1570IPWG4 operates from a single 2.7-V to 5.5-V power supply and is packaged in a 20-pin TSSOP (Thin Shrink Small Outline Package) package, making it suitable for a wide range of applications requiring multiple analog inputs and low power consumption.
