LT1008

Picoamp Input Current,

Microvolt Offset,

Low Noise Op Amp

FEATURES

DESCRIPTIO

The LT^®1008 is a universal precision operational amplifier

that can be used in practically all precision applications.

The LT1008 combines for the first time, picoampere bias

currents (which are maintained over the full –55°C to

125°C temperature range), microvolt offset voltage (and

low drift with time and temperature), low voltage and

current noise, and low power dissipation. Extremely high

common mode and power supply rejection ratios, and the

ability to deliver 5mA load current with high voltage gain

round out the LT1008’s superb precision specifications.

■

Guaranteed Bias Current

T_A= 25°C: 100pA Max

T_A= –55°C to 125°C: 600pA Max

■

Guaranteed Offset Voltage: 120μV Max

■

Guaranteed Drift: 1.5μV/°C Max

■

Low Noise, 0.1Hz to 10Hz: 0.5μV_P-P

■

Guaranteed Low Supply Current: 600μA Max

■

Guaranteed CMRR: 114dB Min

■

Guaranteed PSRR: 114dB Min

Guaranteed Voltage Gain with 5mA Load Current

Available in 8-Lead PDIP and SO Packages

■

The all around excellence of the LT1008 eliminates the

necessity of the time consuming error analysis procedure

of precision system design in many applications; the

LT1008 can be stocked as the universal precision op amp.

APPLICATIO S

■

Precision Instrumentation

Charge Integrators

Wide Dynamic Range Logarithmic Amplifiers

Light Meters

Low Frequency Active Filters

Standard Cell Buffers

Thermocouple Amplifiers

The LT1008 is externally compensated with a single ca-

pacitor for additional flexibility in shaping the frequency

response of the amplifier. It plugs into and upgrades all

standard LM108A/LM308A applications. For an internally

compensated version with even lower offset voltage but

■

otherwise similar performance see the LT1012.
