The LTC®6258/LTC6259/LTC6260 are single/dual/quad n
Low Quiescent Current: 20µA
operational amplifiers with low noise, low power, low n
C-Load™ Op Amp Drives all Capacitive Loads
supply voltage, and rail-to-rail inputs and outputs. They n
Offset Voltage: 400µV Maximum
are unity gain stable with or without capacitive loads. They n
Rail-to-Rail Input and Output
feature 1.3MHz gain-bandwidth product, 0.24V/µs slew rate n
Supply Voltage Range: 1.8V to 5.25V
while consuming only 20µA of supply current per amplifier n
EMI Rejection Ratio: 45dB at 1GHz
operating on supply voltages ranging from 1.8V to 5.25V. n Input Bias Current: 75nA Maximum The combination of low supply current, low supply volt- n CMRR/PSRR: 95dB/90dB age, high gain bandwidth product and low noise makes n Shutdown Current: 7µA Maximum the LTC6258 family unique among rail-to-rail input/output n Operating Temperature Range: –40°C to 125°C op amps with similar supply current. These operational n Single in 6-Lead TSOT-23, 2mm × 2mm DFN amplifiers are ideal for power efficient applications. Packages For applications that require power-down, the LTC6258 n Dual in 8-Lead MS8, MS10, TS0T-23, 2mm × 2mm in 2mm × 2mm DFN and LTC6259 MS10 packages DFN Packages respectively offer shutdown which reduces the current n Quad in MS16 Package consumption to 7µA maximum.
