Preliminary Technical Data Dual Low Power CMOS Analog Front End with DSP Microcomputer AD5744 FEATURES GENERAL DESCRIPTION Complete quad, 14-bit digital-to-analog The AD5744 is a quad, 14-bit, serial input, bipolar voltage converters (DACs) output digital-to-analog converter that operates from supply Programmable output range: ±10 V, ±10.2564 V, or ±10.5263 V voltages of ±11.4 V up to ±16.5 V. Nominal full-scale output ±1 LSB max INL error, ±1 LSB max DNL error range is ±10 V. The AD5744 provides integrated output Low noise: 60 nV/√Hz amplifiers, reference buffers and proprietary power-up/power- Settling time: 10 μs max Integrated reference buffers Output control during power-up/brownout Programmable short-circuit protection Simultaneous updating via LDAC E Asynchronous CLR to zero code Digital gain adjust Logic output control pins T DSP-/microcontroller-compatible serial interface Temperature range: −40°C to +85°C iCMOS™ process technology1 E APPLICATIONS Industrial automation Open-/closed-loop servo control L Process control Data acquisition systems Automatic test equipment Automotive test and measurement OBSO High accuracy instrumentation down control circuitry. The part also features a digital I/O port, which is programmed via the serial interface. The AD5744 incorporates digital gain adjust registers per channel. The AD5744 is a high performance converter that offers guaranteed monotonicity, integral nonlinearity (INL) of ±1 LSB, low noise, and 10 μs settling time. During power-up (when the supply voltages are changing), VOUT is clamped to 0 V via a low impedance path. The AD5744 uses a serial interface that operates at clock rates of up to 30 MHz and is compatible with DSP and microcontroller interface standards. Double buffering allows the simultaneous updating of all DACs. The input coding is programmable to either twos complement or offset binary formats. The asynchronous clear function clears all DAC registers to either bipolar zero or zero scale depending on the coding used. The AD5744 is ideal for both closed-loop servo control and openloop control applications. The AD5744 is available in a 32-lead TQFP, and offers guaranteed specifications over the −40°C to +85°C industrial temperature range. See Figure 1, the functional block diagram. Table 1. Related Devices Part No. AD5744R AD5764 AD5764R Description AD5744 with Internal voltage reference Complete Quad, 16-Bit, High Accuracy, Serial Input, Bipolar Voltage Output DACs AD5764 with internal voltage reference 1 For analog systems designers within industrial/instrumentation equipment OEMs who need high performance ICs at higher voltage levels, iCMOS is a technology platform that enables the development of analog ICs capable of 30 V and operating at ±15 V supplies while allowing dramatic reductions in power consumption and package size, and increased AC and DC performance.
