AD7729ARU-REEL7

ADC Dual Delta-Sigma 13MSPS 15Bit Serial 28Pin TSSOP T/R

Product Details

This monolithic 3 V CMOS device is a low power, two-channel, input port with signal conditioning. The receive path is composed of two, high-performance sigma-delta ADCs with digital filtering. A common bandgap reference feeds the ADCs. A control DAC is included for such functions as AGC. The auxiliary functions can be accessed via the auxiliary port ASPORT. The maximum output word rate is 270 kHz.

The device is available in a 28-pin TSSOP package and a 28-pin SOIC package.
