LTC6261/LTC6262/LTC6263 30MHz, 240µA Power Efficient Rail-to-Rail I/O Op Amps
FeAtures Description
n
Gain Bandwidth Product: 30MHz
The LTC®6261/LTC6262/LTC6263 are single/dual/quad op- n
Low Quiescent Current: 240µA
erational amplifiers with low noise, low power, low supply n
Op Amp Drives up to 1nF Capacitive Loads
voltage, and rail-to-rail inputs and outputs. They are unity n
Offset Voltage: 400µV Maximum
gain stable with capacitive loads up to 1nF. They feature n
Rail-to-Rail Input and Output
30MHz gain-bandwidth product, 7V/µs slew rate while n
Supply Voltage Range: 1.8V to 5.25V
consuming only 240µA of supply current per amplifier n Input Bias Current: 100nA Maximum operating on supply voltages ranging from 1.8V to 5.25V. n CMRR/PSRR: 100dB/95dB The combination of low supply current, low supply voltage, n Shutdown Current: 10µA Maximum high gain bandwidth product and low noise makes the n Operating Temperature Range: –40°C to 125°C LTC6261 family unique among rail-to-rail input/output op n Single in 6-Lead TSOT-23, 2mm × 2mm DFN amps with similar supply current. These operational ampli- Packages fiers are ideal for low power and low noise applications. n Dual in 8-Lead MS8, MS10, TS0T-23, 2mm × 2mm For applications that require power-down, the LTC6261 DFN Packages and LTC6262 in MSOP-10 offer shutdown which reduces n Quad in MS16 Package the current consumption to 10µA maximum.
