GENERAL DESCRIPTION
The AD7457 is a 12-bit, low power, successive approximation (SAR) analog-to-digital converter that features a pseudo differential analog input. This part operates from a single 2.7 V to 5.25 V power supply and features throughput rates of up to 100 k SPS.
The part contains a low noise, wide bandwidth, differential track-and-hold (T/H) amplifier that can handle input...
