DA DAC8802 C8 802 www.ti.com SBAS351B – AUGUST 2005 – REVISED FEBRUARY 2007 Dual, Serial Input 14-Bit Multiplying Digital-to-Analog Converter
FEATURES DESCRIPTION The DAC8802 is a dual, 14-bit, current-output
digital-to-analog converter (DAC) designed to
operate from a single 2.7 V to 5.5 V supply. Relative Accuracy: 1 LSB Max
Differential Nonlinearity: 1 LSB Max
2-mA Full-Scale Current В±20%,
with VREF = В±10 V
0.5 Вµs Settling Time
Midscale or Zero-Scale Reset
Separate 4Q Multiplying Reference Inputs
Reference Bandwidth: 10 MHz
Reference Dynamics: –105 dB THD
SPIв„ў-Compatible 3-Wire Interface:
50 MHz
Double Buffered Registers to Enable
Simultaneous Multichannel Update
Internal Power-On Reset
Industry-Standard Pin Configuration The applied external reference input voltage VREF
determines the full-scale output current. An internal
feedback resistor (RFB) provides temperature
tracking for the full-scale output when combined with
an external I-to-V precision amplifier.
A doubled-buffered, serial data interface offers …
