Description

The 16-bit AD7383-4 and 14-bit AD7384-4 are pin-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 analog input type is a pseudo differential and is sampled and converted on the falling edge of CS.The AD7383-4/AD7384-4 have on-chip oversampling blocks to improve dynamic range and reduce noise at lower bandwidths. The oversampling boosts up to two bits of added resolution. A buffered 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 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 devices are compatible with 1.8 V, 2.5 V, and 3.3 V interfaces using the separate logic supply.The AD7383-4/AD7384-4 are available in a 24-lead, 4 mm × 4 mm LFCSP and a temperature range of −40°C to +125°C.ApplicationsMotor control position feedbackMotor control current senseData acquisition systemsErbium-doped fiber amplifier (EDFA) applicationsInphase and quadrature demodulationProduct HighlightsQuad simultaneous sampling and conversion.Pin-compatible product family.High 4 MSPS throughput rate.Space-saving 4 mm × 4 mm LFCSP.Integrated oversampling block to increase dynamic range, reduce noise, and reduce SCLK speed requirements.Pseudo differential analog inputs.Small sampling capacitor reduces amplifier drive burden.
