Description

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. APPLICATIONS Motor control position feedback Motor control current sense Data acquisition systems Erbium doped fiber amplifier (EDFA) applications In phase and quadrature demodulationPRODUCT HIGHLIGHTS Quad simultaneous sampling and conversion Pin-compatible product family. High throughput rate, 4 MSPS at 16-bit. Space-saving, 4 mm ? 4 mm LFCSP. Integrated oversampling block to increase dynamic range, reduce noise and reduce SCLK speed requirements. Differential analog inputs with wide common-mode range. Small sampling capacitor reduces amplifier drive burden.
