AD4003 - Precision SAR Differential ADC

Download the AD4003 datasheet PDF. This datasheet also covers the AD4003-1 variant, as both devices belong to the same precision sar differential adc family and are provided as variant models within a single manufacturer datasheet.

General Description

The AD4003/AD4007/AD4011 are high accuracy, high speed, low power, 18-bit, Easy Drive, precision successive approximation register (SAR) analog-to-digital converters (ADCs) that operate from a single power supply, VDD.

Key Features

  • Easy Drive Greatly reduced input kickback Input current reduced to 0.5 μA/MSPS Enhanced acquisition phase, ≥79% of cycle time at 1 MSPS First conversion accurate, no latency or pipeline delay Input span compression for single-supply operation Fast conversion allows low SPI clock rates Input overvoltage clamp protection sinks up to 50 mA SPI-/QSPI-/.
