ADS7945SRTER

14位， 2 MSPS ，双通道，差分/单端，超低功耗模拟 - 数字转换器 14-Bit, 2 MSPS, Dual-Channel, Differential/Single-Ended, Ultralow-Power Analog-to-Digital Converters

The ADS7945/6 are 14-bit, 2 MSPS analog-to-digital converters ADCs, with differential and single-ended inputs, respectively. The devices operate at a 2 MSPS sample rate with a standard 16-clock data frame. The devices feature both outstanding dc precision and excellent dynamic performance; the ADS7946 is pin-compatible with the 8/10/12-bit ADS7947/8/9 devices. The devices include 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 ADS7945/6 support a wide analog supply range that allows the full-scale input range to extend to ±5 V differential or 5 V single-ended. A simple SPI™, with a digital supply that can operate as low as 1.65 V, 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 3 mm × 3 mm QFN package, the ADS7945/6 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 package size are key.
