DAC7554 www.ti.com SLAS399A–OCTOBER 2004–REVISED NOVEMBER 2004 12-BIT, QUAD, ULTRALOW GLITCH, VOLTAGE OUTPUT DIGITAL-TO-ANALOG CONVERTER FEATURES DESCRIPTION • 2.7-V to 5.5-V Single Supply The DAC7554 is a quad-channel, voltage-output DAC with exceptional linearity and monotonicity. Its pro- • 12-Bit Linearity and Monotonicity prietary architecture minimizes undesired transients • Rail-to-Rail Voltage Output such as code to code glitch and channel to channel • Settling Time: 5µs (Max) crosstalk. The low-power DAC7554 operates from a • Ultralow Glitch Energy: 0.1 nVs single 2.7-V to 5.5-V supply. The DAC7554 output amplifiers can drive a 2-kΩ, 200-pF load rail-to-rail • Ultralow Crosstalk: –100 dB with 5-µs settling time; the output range is set using • Low Power: 880µA (Max) an external voltage reference. • Per-Channel Power Down: 2µA (Max) The 3-wire serial interface operates at clock rates up • Power-On Reset to Zero Scale to 50 MHz and is compatible with SPI, QSPI, • SPI-Compatible Serial Interface: Up to 50 MHz Microwire, and DSP interface standards. The outputs of all DACs may be updated simultaneously or • Simultaneous or Sequential Update sequentially. The parts incorporate a power-on-reset • Specified Temperature Range: –40°C to 105°C circuit to ensure that the DAC outputs power up to • Small 10-Lead MSOP Package zero volts and remain there until a valid write cycle to the device takes place. The parts contain a power-down feature that reduces the current con- APPLICATIONS sumption of the device to under 1µA. • Portable Battery-Powered Instruments • Digital Gain and Offset Adjustment The small size and low-power operation makes the DAC7554 ideally suited for battery-operated portable • Programmable Voltage and Current Sources applications. The power consumption is typically 3.5 • Programmable Attenuators mW at 5 V, 1.65 mW at 3 V, and reduces to 1µW in • Industrial Process Control power-down mode. The DAC7554 is available in a 10-lead MSOP pack- age and is specified over –40°C to 105°C.
