LTC1662
Ultralow Power, Dual
10-Bit DAC in MSOP
Features Description Ultralow Power: 1.5ВµA (Typ) ICC per DAC Plus
0.05ВµA Sleep Mode for Extended Battery Life
n Tiny: Two 10-Bit DACs in an 8-Lead MSOP—
Half the Size of an SO-8
n Wide 2.7V to 5.5V Supply Range
n Double Buffered for Simultaneous DAC Updates
n Rail-to-Rail Voltage Outputs Drive 1000pF
n Reference Range Includes Supply for Ratiometric
0V to VCC Output
n Reference Input Impedance Is Code-Independent
(7.1MΩ Typ)—Eliminates External Buffers
n 3-Wire Serial Interface with Schmitt Trigger Inputs
n Differential Nonlinearity: В±0.75LSB Max The LTCВ®1662 is an ultralow power, fully buffered voltage
output, dual 10-bit digital-to-analog converter (DAC). Each
DAC channel draws just 1.7ВµA (typ) total supply-plusreference operating current, yet is capable of supplying
DC output currents in excess of 1mA and reliably driving
capacitive loads of up to 1000pF. A programmable sleep
mode further reduces total operating current to 0.05ВµA. n Applications n n n Mobile Communications
