AD7091R-5 - 12-Bit ADC

Description

The AD7091R-5 is a 12-bit, multichannel, ultra low power, successive approximation analog-to-digital converter (ADC).

The AD7091R-5 operates from a single 2.7 V to 5.25 V power supply and typically consumes only 24 µA at a 3 V supply in fast mode.

Features

  • I2C-compatible serial interface supports standard and fast modes Ultra low power: 90 µW typical at 3 V in fast mode Specified for VDD of 2.7 V to 5.25 V On-chip accurate 2.5 V reference, 5 ppm/°C typical drift 4 single-ended analog input channels ALERT function BUSY function Autocycle mode Wide input bandwidth 68 dB signal-to-noise ratio (SNR) typical at input frequency of 1 kHz Flexible power/throughput rate management No pipeline delays Power-down mode 550 nA typical at VDD = 5.25 V 435 nA typ.
