AD7457BRTZ

• Product introduction

AD7457BRTZ Pseudo-differential input, 100 kSPS, 12-bit ADC in 8-lead SOT-23 The AD7457 is a 12-bit, low-power, successive approximation (SAR) analog-to-numberconverter(ADC) with pseudo-differential analog inputs, operating from a single 2.7V to 5.25V supply and up to 100 kSPS.

The conversion process and the data acquisition process pass.CSand the serial clock to create the conditions for the device to interface with a microprocessor or DSP.

These devices feature a SAR architecture that ensures no pipeline delay.

The AD7457 uses advanced design techniques to achieve very low power consumption.
