2.5 V internal reference at 10 ppm/°C (maximum)
24-lead LFCSP

The AD7386-4/AD7387-4/AD7388-4 are 16-bit, 14-bit, and 12-bit compatible, quad, simultaneous sampling, high-speed, successive approximation register (SAR), analog-to-digital converters (ADCs) operating from a 3.0 V to 3.3 V power supply with throughput rates up to 4 MSPS. The single-ended analog input accepts voltage from 0 V to V_REF, and is sampled and converted on the falling edge of CS.

The AD7386-4/AD7387-4/AD7388-4 have on-chip oversampling blocks to improve dynamic range and reduce noise at lower bandwidths. The oversampling can boost up to two bits of added resolution. The REFIO pin can have a reference voltage (V_REF) of 2.5 V to 3.3 V.

The conversion process and data acquisition use standard control inputs, allowing easy interfacing to microprocessors or digital signal processors (DSPs). The conversion result can clock out simultaneously via 4-wire mode for faster throughput or via 1-wire serial mode when slower throughput is allowed. The device is compatible with 1.8 V, 2.5 V, and 3.3 V interfaces using the separate logic supply.

The AD7386-4/AD7387-4/AD7388-4 are available in a 24-lead lead frame chip scale package (LFCSP) and operate over a temperature range of −40°C to +125°C

Product Details

The EVAL-AD7386-4FMCZ is a full featured evaluation board that evaluates all features of the AD7386-4 analog-to-digital converters (ADCs). The evaluation board can be controlled by the EVAL-SDPCH1Z via the 160-way system demonstration platform (SDP) connector, J4. The EVAL-SDP-CH1Z board controls the evaluation board through the USB port of a PC using the analysis, control, evaluation (ACE) software, which is available for download from the ACE software page.

Complete specifications for the AD7386-4 is provided in the AD7386-4 data sheet. Consult these specifications in conjunction with this 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.

The EVAL-AD7386-4FMCZ can evaluate the AD7387-4 and the AD7388-4 by using the AD738x-4 ACE plugin found on the EVALAD7386- 4FMCZ 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.

Figure 1 shows the typical setup of the EVAL-AD7386-4FMCZ board. The setup for the EVAL-AD7386-4FMCZ board is the same as the EVAL-AD7380-4FMCZ setup.
