ADS7229IPWR

Analog To Digital Converters (ADC) Overview

The ADS7229IPWR is a low-power, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-channel SAR architecture with a sampling rate of 1 MSPS and supports single-ended inputs. The device operates with an analog supply voltage range of 2.7 V to 5.5 V and a digital I/O supply range of 1.65 V to 5.5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 73.9 dB, differential nonlinearity (DNL) of ±0.5 LSB maximum, and integral nonlinearity (INL) of ±0.5 LSB maximum. It consumes 13.7 mW at 1 MHz with a 3 V analog supply. The component is housed in a TSSOP-16 package and functions within an industrial temperature range of -40°C to +85°C.
