ADS7853IPWR TI SAR ADC Converter 2 Input 2 SAR 16-TSSOP
The ADS7853IPWR is a high-performance, low-power 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments, housed in a 16-TSSOP package. It is engineered to deliver precise and rapid data conversion for demanding measurement applications across industrial, medical, and portable systems, operating from a single 2.7V to 5.5V supply. Its combination of speed, accuracy, low power, and a compact footprint makes it ideal for applications requiring reliable, high-speed analog-to-digital conversion in space-constrained and power-sensitive designs.
This ADC distinguishes itself with a high sampling rate of 500 kSPS (kilo samples per second) and excellent dynamic performance, including a typical signal-to-noise ratio (SNR) of 72 dB. Key features include a flexible differential input range of ±VREF, a low power consumption of just 1.8 mW at 3V and 100 kSPS, and an integrated low-drift 2.5V reference. It offers a versatile input multiplexer supporting two fully differential or four single-ended channels and includes a power-down mode reducing current to 1 µA typical.
