AD7457BRTZ

• Product introduction

AD7457BRTZ   伪差分输入、100 kSPS、12位ADC，采用8引脚SOT-23封装 AD7457是一款12位低功耗、逐次逼近型(SAR)模数converter(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.

• Rated voltage (V_DD ): 2.7 V to 5.25 V
• Very low power consumption:
  - 0.9 mW maximum (100 kSPS, V_DD = 3V）
  - 3 mW maximum (100 kSPS, V_DD = 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
