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 VREF, 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 (VREF) 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
