ADS7817E/250 Description

Short technical summary and product information.

The ADS7817E/250 is a 12-bit, 200ksps sampling analog-to-digital converter (ADC) from Texas Instruments. It uses a successive approximation register (SAR) architecture and offers a pseudo-differential or single-ended input with an input voltage range of 0V to 5.25V. The device features an SPI serial interface and requires an external reference voltage, which can be varied from 100mV to 2.5V for adjustable resolution.

 

Key electrical specifications include a typical power consumption of 2.3mW at 200ksps, with a power-down mode drawing only 3µA maximum. The signal-to-noise ratio (SNR) is typically 71dB. The ADC operates from analog and digital supply voltages of 4.75V to 5.25V and is specified over a temperature range of -40°C to 85°C.

 

The ADS7817E/250 is housed in an 8-pin VSSOP (MSOP) package and is surface mountable. It is suitable for applications such as transducer interfaces, battery-operated systems, remote data acquisition, isolated data acquisition, and AC motor control.
