ADS7871IDBG4 .

The ADS7871IDBG4 is a 14-bit Data-Acquisition System (DAC) with analog-to-digital converter, MUX, PGA and reference. It is a complete low power data acquisition system on a single chip. It consists of a 4-channel differential/8-channel single-ended multiplexer, precision programmable gain amplifier, 14-bit successive approximation analog-to-digital (A/D) converter and a precision voltage reference. The programmable-gain amplifier provides high input impedance, excellent gain accuracy, good common-mode rejection and low noise. For many low-level signals, no external amplification or impedance buffering is needed between the signal source and the A/D input. The ADC contains an internal reference, which is trimmed for high initial accuracy and stability vs temperature. Drift is typically 10 ppm/°C. An external reference can be used in situations where multiple ADC shares a common reference.
