AD4003BRMZ Part Information
The AD4003 is a low noise, low power, high speed, 18-bit, 2 MSPS precision successive approximation register (SAR) analog-to- digital converter (ADC). It incorporates ease of use features that lower the signal chain power, reduce signal chain complexity, and enable higher channel density. The high-Z mode, coupled with a long acquisition phase, eliminates the need for a dedicated high power, high speed ADC driver, thus broadening the range of low power precision amplifiers that can drive this ADC directly, while still achieving optimum performance. The input span compression feature enables the ADC driver amplifier and the ADC to operate off common supply rails without the need for a negative supply while preserving the full ADC code range. The low serial peripheral interface (SPI) clock rate requirement reduces the digital input/output power consumption, broadens processor options, and simplifies the task of sending data across digital isolation. Operating from a 1.8 V supply, the AD4003 has a ±VREF fully differ- ential input range with VREF ranging from 2.4 V to 5.1 V. The AD4003 consumes only 16 mW at 2 MSPS with a minimum of 75 MHz SCK rate in turbo mode and achieves ±1.0 LSB (±3.8 ppm) INL maximum, guaranteed no missing codes at 18 bits with 100.5 dB typical SNR. The reference voltage is applied externally and can be set independently of the supply voltage. The SPI-compatible versatile serial interface features seven different modes including the ability, using the SDI input, to daisy-chain several ADCs on a single 3-wire bus and provides an optional busy indicator. The AD4003 is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic, using the separate VIO supply. The AD4003 is available in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +125°C. The device is pin compatible with the 16-bit, 2 MSPS AD4000.
