The ADS7948SRTER from Texas Instruments is a 10-bit successive-approximation-register (SAR) analog-to-digital converter capable of sampling at rates up to 2 MSPS. The device provides two multiplexed input channels that can be used in pseudo-differential or single-ended configurations. A standard SPI-compatible serial interface makes it straightforward to connect to host controllers. The ADS7948 belongs to the pin-compatible ADS794x family of 12-, 10-, and 8-bit ADCs from Texas Instruments.
Key performance characteristics include a typical signal-to-noise ratio of 61 dB, maximum integral nonlinearity of 1 LSB, and no missing codes across the input range. At 2 MSPS, the typical power consumption is 7.5 mW, with automatic power-down reducing power to 3.8 mW at 500 kSPS, 0.8 mW at 100 kSPS, and 0.16 mW at 20 kSPS. The ADC operates with an external voltage reference and supports analog supplies from 2.7 V to 5.5 V and digital supplies from 1.65 V to 5.5 V.
The ADS7948SRTER comes in a 16-pin WQFN package measuring 3 mm × 3 mm with an exposed pad for thermal relief. It is surface-mountable and operates over an extended temperature range of -40°C to 125°C. These specifications make it suitable for low-power precision data acquisition in portable instrumentation, industrial control, and sensor-interface applications.
