The AD7386/AD7387/AD7388 are 16-bit, 14-bit, and 12-bit dual, simultaneous sampling, high speed, successive approximation register (SAR), analog-to-digital converters (ADCs) that operate from a 3.0 V to 3.6 V power supply and feature throughput rates of up to 4 MSPS. The analog input types are single-ended and are sampled and converted on the falling edge of CS.

The AD7386/AD7387/AD7388 have an on-chip sequencer and integrated on-chip oversampling block to improve dynamic range and reduce noise at lower bandwidths. Abuffered internal 2.5 V reference is included. Alternatively, an external reference up to 3.3 V can be used. The conversion process and data acquisition use standard control inputs, allowing interfacing to microprocessors or digital signal processors (DSPs). The AD7386 is compatible with 1.8 V, 2.5 V, and 3.3 V interfaces by using the separate logic supply.

The AD7386/AD7387/AD7388 are available in a 16-lead LFCSP with operation specified from −40°C to +125°C.

Product Highlights

  1. 4-channel, dual simultaneous sampling ADC.
  2. Pin-compatible product family.
  3. High 4 MSPS throughput rate.
  4. Space-saving 3 mm × 3 mm LFCSP.
  5. Integrated oversampling block to increase dynamic range and SNR and to reduce SCLK speed requirements.
  6. Single-ended analog inputs.
  7. Small sampling capacitor reduces amplifier drive burden.

Evaluating the AD7386 4-Channel 16-Bit, Dual Simultaneous Sampling, SAR ADC

Features and Benefits

  • Full featured evaluation board multichannel, simultaneous sampling ADC
  • On-board reference, reference buffer, and ADC driver
  • On-board power supplies
  • Board-compatible high speed system demonstration platform (EVAL-SDP-CH1Z (SDP-H1)) controller
  • PC software for control and data analysis 

Product Detail

The EVAL-AD7386FMCZ is a full featured evaluation board designed to evaluate all the features of the AD7386 analog-to-digital converter (ADC). The evaluation board can be controlled by the EVAL-SDP-CH1Z via the 160-way system demonstration platform connector, P7. The EVAL-SDP-CH1Z board controls the evaluation board through the USB port of the PC using the Analysis Control Evaluation (ACE) software, which is available for download from the ACE software page.

The EVAL-AD7386FMCZ can evaluate the AD7387, AD7388, AD4684, and AD4685 by using the AD738x ACE plugin found on the EVAL-AD7386FMCZ product page. The only difference is the number of SCLKs that clock out the conversion results, which is dependent on the resolution and throughput rate for each generic.

Complete specifications for the AD7386, AD7387, AD7388, AD4684, and AD4685 are provided in the AD7386/AD7387/AD7388 and AD4684/AD4685 data sheets. Consult these specifications in conjunction with the user guide when using the evaluation board. Full details on the EVAL-SDP-CH1Z are available on the SDP-H1 product page. The comprehensive ACE user guide is available on the ACE software page.
