The output amplifier • Extended Power Supply Range (+2.7V to allows rail-to-rail output swing and has an 6µsec +5.5V) settling time. The DAC101C081 uses the supply voltage as the reference to provide the widest • I2C-Compatible 2-Wire Interface which dynamic output range and typically consumes 132µA Supports Standard (100kHz), Fast (400kHz), while operating at 5.0V. It is available in 6-lead SOT and High Speed (3.4MHz) Modes and WSON packages and provides three address • Rail-to-Rail Voltage Output options (pin selectable). • Very Small Package As an alternative, the DAC101C085 provides nine • DAC101C081Q is AEC Q100 Grade 1 Qualified I2C™ addressing options and uses an external and Manufactured on Automotive Grade Flow reference. It has the same performance and settling time as the DAC101C081. It is available in an 8-lead VSSOP. KEY SPECIFICATIONS The DAC101C081 and DAC101C085 use a 2-wire, • Resolution: 10 bits I2C™-compatible serial interface that operates in all • INL: ±2 LSB (max) three speed modes, including high speed mode • DNL: +0.3/-0.2 LSB (max) (3.4MHz). An external address selection pin allows up • Setting Time: 6 µs (max) to three DAC101C081 or nine DAC101C085 devices per 2-wire bus. Pin compatible alternatives to the • Zero Code Error: +10 mV (max) DAC101C081 are available that provide additional • Full-Scale Error: −0.7 %FS (max) address options. • Supply Power (Normal): 380 µW (3V) / 730 µW The DAC101C081 and DAC101C085 each have a (5V) typ 16-bit register that controls the mode of operation, the • Supply Power (Power Down): 0.5 µW (3V) / 0.9 power-down condition, and the output voltage. A µW (5V) typ power-on reset circuit ensures that the DAC output powers up to zero volts. A power-down feature reduces power consumption to less than a microWatt. APPLICATIONS Their low power consumption and small packages • Industrial Process Control make these DACs an excellent choice for use in • Portable Instruments battery operated equipment. Each DAC operates over the extended industrial temperature range of −40°C • Digital Gain and Offset Adjustment to +125°C. • Programmable Voltage & Current Sources The DAC101C081 and DAC101C085 are each part of • Test Equipment a family of pin compatible DACs that also provide 12 • Automotive and 8 bit resolution. For 12-bit DACs see the DAC121C081 and DAC121C085. For 8-bit DACs see the DAC081C081 and DAC081C085. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 I2C is a trademark of NXP Semiconductors. 3 All other trademarks are the property of their respective owners.
