General Description
The AD5371 contains 40, 14-bit DACs in a single, 80-lead,
LQFP package. It provides buffered voltage outputs with a span
4 times the reference voltage. The gain and offset of each DAC
can be independently trimmed to remove errors. For even
greater flexibility, the device is divided into blocks of 8 DACs,
and the output range of each block can be independently
adjusted by an offset DAC. Group 0 can be adjusted by Offset
DAC 0, group 1 can be adjusted by Offset DAC 1 and group 2 to
group 4 can be adjusted by Offset DAC 2.
The AD5371 offers guaranteed operation over a wide supply
range with VSS from -4.5 V to -16.5 V and VDD from +8 V to
+16.5 V. The output amplifier headroom requirement is 1.4 V
operating with a load current of 1 mA.
The AD5371 has a high-speed serial interface, which is
compatible with SPI®, QSPI™, MICROWIRE™, and DSP
interface standards and can handle clock speeds of up to 50
MHz. It also has a 100 MHz Low Voltage Differential Signaling
(LVDS) serial interface compliant with EIA-644 specification.
The DAC outputs are updated on reception of new data into the
DAC registers. All the outputs can be updated simultaneously
by taking the LDAC input low. Each channel has a program-
mable gain and an offset adjust register.
Each DAC output is amplified and buffered on-chip with
respect to an external SIGGND input. The DAC outputs can
also be switched to SIGGND via the CLR pin.
