  • Product introduction

AD7457BRT-R2 pseudo differential input, 100 kSPS, 12-bit ADC in 8-lead SOT-23 package The AD7457 is a 12-bit, low power, successive approximation (SAR) modulusconverter(ADC) with pseudo-differential analog inputs, operating from a single 2.7V to 5.25V supply and up to 100 kSPS.

The device includes a low noise, wide bandwidth, differential sample/hold amplifier (T/H) that handles input frequencies above 1 MHz. The reference voltage of the AD7457 is externally applied to the VREF pin over a voltage range of 100mV to VDD , depending on the application.

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.

  • Rated voltage (VDD ): 2.7 V to 5.25 V
  • Very low power consumption:
    - 0.9 mW maximum (100 kSPS, VDD = 3V）
    - 3 mW maximum (100 kSPS, VDD = 5V）
  • Pseudo-differential analog input
  • Signal-to-Ratio: 70 dB at 30 kHz input frequency
  • No pipeline delay
  • Serial interface
    - SPI®/QSPI™/MICROWIRE™/DSP
    compatible
  • Automatic power saving mode
  • 8-pin SOT-23 package
