AD7453 datasheet



The AD7453 is a 12-bit, high speed, low power, successive approximation (SAR) analog-to-digital converter that features a pseudo differential analog input. This partoperates from a single 2.7 V to5.25 V power supply and featuresthroughput rates upto555 kSPS.
The part contains alow noise, wide bandwidth,differential track-and-hold amplifier(T/H) that can handle input frequencies upto3.5 MHz.

The reference voltage for the AD7453 is applied externally to the VREF pin and can range from 100 mV to VDD,depending onthe power supply and whatsuits the application.
