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 up to 100 kSPS.
The part contains a low-noise, wide bandwidth, differential track and hold amplifier (T/H) which can handle input frequencies in excess of 1 MHz. The reference voltage for the AD7457 is applied externally to the VREF pin and can range from 100mV to VDD, depending on what suits the application.
The conversion process and data acquisition are controlled using 
and the serial clock allowing the device to interface with Microprocessors or DSPs.
The SAR architecture of these parts ensures that there are no pipeline delays.
The AD7457 uses advanced design techniques to achieve very low power dissipation.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
