GENERAL DESCRIPTION
The AD5764R is a quad, 16-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 AD5764R 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 AD5764R is a high performance converter that provides
guaranteed monotonicity, integral nonlinearity (INL) of ±1 LSB,
low noise, and 10 μs settling time. The AD5764R 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 AD5764R is based on the iCMOS technology platform,
which is designed for analog systems designers within industrial/
instrumentation equipment OEMs who need high performance
ICs at higher voltage levels. iCMOS enables the development of
analog 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 AD5764R 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 AD5764R is ideal for both
closed-loop servo control and open-loop control applications.
The AD5764R 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).
