The AD7380-4 is a 16-bit compatible, quad, simultaneous sampling, high speed, successive approximation register (SAR), analog-to-digital converters (ADC) operating from a 3.3 V power supply with throughput rates up to 4 MSPS. The differential analog input accepts a wide common-mode input voltage and is sampled and converted on the falling edge of CS.
The AD7380-4 has 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 REFIN pin can have a reference voltage 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 AD7380-4 is available in a 24-lead lead frame chip scale package (LFCSP) and operates over a temperature range of −40°C to +125°C.

Evaluation Kits (1)
The EVAL-AD7380-4FMCZ and EVAL-AD7383-4FMCZ are full featured evaluation boards that evaluate all features of the AD7380-4 and AD7383-4 analog-to-digital converters (ADCs). The evaluation boards can be controlled by the EVAL-SDP-CH1Z via the 160-way system demonstration platform (SDP) connector, J4. The EVALSDP-CH1Z board controls the evaluation boards 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 AD7380-4, AD7381-4, AD7389-4, AD7384-4, and AD7383-4 are provided in the AD7380-4, AD7381-4, AD7389-4, AD7384-4, and AD7383-4 data sheets. Consult these specifications in conjunction with this user guide when using the evaluation boards. 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-AD7380-4FMCZ can be used to evaluate the AD7389-4 and AD7381-4. The EVAL-AD7383-4FMCZ can be used to evaluate the AD7384-4. 14-bit ADCs like the AD7381-4 and AD7384-4 have a lower number of SCLK cycles to clock out the conversion result. Refer to the product data sheet for information about the serial interface and for the required number of serial clock (SCLK) reading conversion results.
