LTC1662CMS8#PBF

LTC®1662 is an ultralow power fully buffered voltage output dual 10-bit digital-to-analogue converter (DAC). A programmable sleep mode further reduces total operating current to 0.05µA. It provides excellent linearity and an exceptionally small external form factor. This double-buffered input logic provides simultaneous update capability and can be used to write to the DACs without interrupting sleep mode. With its tiny operating current and exceptionally small size. Ideal for use in the most power constrained products. For most designs, there is no perceptible impact on the power budget. Applications are mobile communications, portable battery-powered instruments, remote or inaccessible adjustments, digitally controlled amplifiers and attenuators, factory or field calibration.

• Ultralow power is1.5µA (typical) ICC per DAC plus, 0.05µA sleep mode for extended battery life
• Wide 2.7V to 5.5V supply range
• Double buffered for simultaneous DAC updates
• Rail-to-rail voltage outputs drive 1000pF
• Reference input impedance is code-independent (7.1Mohm typical)-eliminates external buffers
• 3-wire serial interface with schmitt trigger inputs
• Differential nonlinearity is ±0.75LSB maximum
• 8-lead plastic MSOP package
• 0°C to 70°C temperature range
