High Impedance Transducer Amplifi er
The LTC®6240/6241/LTC6242 are single, dual and quad
low noise, low offset, rail-to-rail output, unity gain stable
CMOS op amps that feature 1pA of input bias current. Input
bias current is guaranteed to be 1pA max on the single
LTC6240. The 0.1Hz to 10Hz noise of only 550nV
, along
P-P
with an offset of just 125µV are signifi cant improvements
over traditional CMOS op amps. Additionally, noise is
guaranteed to be less than 10nV/√Hz at 1kHz. An 18MHz
gain bandwidth, and 10V/µs slew rate, along with the wide
supply range and low input capacitance, make them perfect
for use as fast signal processing amplifi ers.
These op amps have an output stage that swings within
30mV of either supply rail to maximize the signal dynamic
range in low supply applications. The input common mode
range extends to the negative supply. They are fully specifi ed on 3V and 5V, and an HV version guarantees operation
on supplies up to ±5V.
The LTC6240 is available in the 8-pin SO and the 5-pin
SOT-23 packages. The LTC6241 is available in the 8-pin
SO, and for compact designs it is packaged in a tiny dual
fi ne pitch leadless (DFN) package. The LTC6242 is available in the 16-Pin SSOP as well as the 5mm × 3mm DFN
package.
