ADS7948SRTET-10-Bit, 2 MSPS, Dual Channel, Pseudo-differential uPower Serial SAR ADC

The ADS7947/8/9 are 12-bit, 10-bit, and 8-bit 2MSPS analog-to-digital converters (ADCs), respectively. Devices operate at 2MSPS sample rate with a standard 16 clock data frame. In addition, it is possible to operate the ADS7947 (12-bit) at 2.1MSPS, the ADS7948 (10-bit) at 2.57MSPS, and the ADS7949 (8-bit) at 3MSPS with a short data frame optimized for the number of clocks sufficient for conversion with no drop in performance. The devices feature both outstanding dc precision and excellent dynamic performance, this family of pin-compatible devices includes a two-channel input multiplexer and a low-power successive approximation register (SAR) ADC with an inherent sample-and-hold (S/H) input stage.

The ADS7947/8/9 support a wide analog supply range that allows the full-scale input range to extend to 5V. A simple SPI, with a digital supply that can operate as low as 1.65V, allows for easy interfacing to a wide variety of digital controllers. Automatic power-down can be enabled when operating at slower speeds to dramatically reduce power consumption.

Offered in a tiny 3mm × 3mm QFN package, the ADS7947/8/9 are fully specified over the extended temperature range of –40°C to +125°C and are suitable for a wide variety of data acquisition applications where high performance, low power, and small size are key.
