LTC1661IMS8#TRPBF

LTC1661 is a micropower dual, 10-bit DAC. Each buffered DAC draws just 60µA total supply current, yet is capable of supplying DC output currents in excess of 5mA and reliably driving capacitive loads upto 1000pF. Sleep mode further reduces total supply current to a negligible 1µA. The double-buffered input logic provides simultaneous update capability and can be used to write to either DAC without interrupting sleep mode. Ultralow supply current, power-saving sleep mode and extremely compact size make the device ideal for battery-powered applications, while its straightforward usability, high performance and wide supply range make it an excellent choice as a general purpose converter. It is widely used in application such as mobile communications, digitally controlled amplifiers and attenuators, portable battery-powered instruments, automatic calibration for manufacturing, remote industrial devices etc.

• Sleep mode is 1µA for extended battery life
• Wide supply voltage range is 2.7V to 5.5V
• Reference range includes supply for ratiometric 0V-to-VCC output
• 3-sire serial interface with Schmitt trigger inputs
• Reference input has constant impedance over all codes (260K ohm typ)—eliminates external buffers
• Differential nonlinearity is ±0.1LSB typical
• Offset error is ±5mV typical
• Power supply rejection ratio is 0.18LSB/V typical at (VREF = 2.5V)
• Operating temperature is -40°C to 85°C
• Packaging style is 8-lead plastic MSOP
