AD7706BRZ-REEL Datasheet PDF - ADI

Product Details

●The AD7705 and AD7706 are complete 16-bit, low-cost, Sigma Delta ADCs intended for dc and low-frequency ac measurement applications. Their low power (1 mW max @ 3 V) allows them to be used in loop-powered, battery-powered or locally-powered applications. The on-chip Programmable Gain Amplifier with gain settings from I through 128 can accommodate both low-level and high-level analog inputs with no external signal conditioning hardware.

●The AD7705 has two differential channels while the AD7706 has one differential and two pseudo-differential channels. Differential reference inputs also allow maximum flexibility in tailoring the device for use in ratiometric applications.
