LT1677

Low Noise, Rail-to-Rail

Precision Op Amp

FEATURES

DESCRIPTIO

The LT^®1677 features the lowest noise performance avail-

able for a rail-to-rail operational amplifier: 3.2nV/√Hz

wideband noise, 1/f corner frequency of 13Hz and 90nV

peak-to-peak 0.1Hz to 10Hz noise. Low noise is combined

with outstanding precision: 20µV offset voltage and

0.2µV/°C drift, 130dB common mode and power supply

rejection and 7.2MHz gain bandwidth product. The com-

mon mode range exceeds the power supply by 100mV.

■

Rail-to-Rail Input and Output

100% Tested Low Voltage Noise:

■

3.2nV/√Hz Typ at 1kHz

4.5nV/√Hz Max at 1kHz

■

Offset Voltage: 60µV Max

■

Low V_OSDrift: 0.2µV/°C Typ

■

Low Input Bias Current: 20nA Max

■

Wide Supply Range: 3V to ±18V

■

High A_VOL: 7V/µV Min, R_L= 10k

The voltage gain of the LT1677 is extremely high, 19 million

(typical) driving a 10k load.

■

High CMRR: 109dB Min

■

High PSRR: 108dB Min

In the design, processing and testing of the device, particular

attention has been paid to the optimization of the entire

distribution of several key parameters. Consequently, the

specifications have been spectacularly improved compared

to competing rail-to-rail amplifiers.

■

Gain Bandwidth Product: 7.2MHz

■

Slew Rate: 2.5V/µs

■

Operating Temperature Range: –40°C to 85°C
