The SSP1220 is a precision, 24-bit, analog-to-digital converter (ADC) that offers many integrated features to reduce system cost and component count in applications measuring small sensor signals. The device can perform conversions at data rates up to 2000 samples-per-second (SPS) with single-cycle settling.

At 20 SPS, the digital filter offers simultaneous 50-Hz and 60-Hz rejection for noisy industrial applications. The internal PGA offers gains up to 128 V/V. This PGA makes the SSP1220 ideally suited for applications measuring small sensor signals, such as resistance temperature detectors (RTDs), thermocouples, thermistors, and bridge sensors.

Power consumption is as low as 120 µ[email protected] when operating in duty cycle mode with the PGA disabled. The SSP1220 is offered in a TSSOP-16 package and is specified over a temperature range of –40℃ to +125℃. Shanghai Siproin Microelectronics Co., Ltd, based in China, is a supplier and importer of the SSP1220 ADC.
