GENERAL DESCRIPTION
The AD5744R is a quad, 14-bit, serial input, bipolar voltage output
DAC that operates from supply voltages of ±11.4 V to ±16.5 V.
Nominal full-scale output range is ±10 V. The AD5744R provides
integrated output amplifiers, reference buffers, and proprietary
power-up/power-down control circuitry. The part also features
a digital I/O port, programmed via the serial interface, and an
analog temperature sensor. The part incorporates digital offset
and gain adjust registers per channel.
The AD5744R is a high performance converter that provides
guaranteed monotonicity, integral nonlinearity (INL) of ±1 LSB,
low noise, and 10 μs settling time. The AD5744R includes an on-
chip 5 V reference with a reference temperature coefficient of
10 ppm/°C maximum. During power-up when the supply voltages
are changing, VOUTx is clamped to 0 V via a low impedance path.
The AD5744R is based on the iCMOS technology platform, which
is designed for analog systems designers within industrial/instru-
mentation equipment OEMs who need high performance ICs at
ICs capable of 30 V and operation at ±15 V supplies, while allowing
reductions in power consumption and package size, coupled with
increased ac and dc performance.
The AD5744R 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 DATA registers to either bipolar zero or zero
scale, depending on the coding used. The AD5744R is ideal for
both closed-loop servo control and open-loop control applications.
The AD5744R is available in a 32-lead TQFP and offers guaranteed
specifications over the 40°C to +85°C industrial temperature
range (see Figure 1 for the functional block diagram).
