LT1464/LT1465

Dual/Quad Micropower,

1MHz C-Load Picoampere

Bias Current JFET Input Op Amps

FEATURES

DESCRIPTION

The LT^®1464 (dual) and LT1465 (quad) are the first

micropower op amps (200µA max per amp) to offer

picoampereinputbiascurrents(500fAtyp)andunity-gain

stability for capacitive loads up to 10nF. The output can

swing a 10k load to within 1.5V of either supply, just like

op amps that require an order of magnitude more supply

current. This unique combination of performance makes

the LT1464/LT1465 ideal over a wide range of input and

output impedances.

■

Input Bias Current:

2pA Max (LT1464A)

20pA Max (LT1464, LT1465)

■

Supply Current per Amplifier: 200µA Max

■

Gain Bandwidth Product: 1MHz Typ

Slew Rate: 0.9V/µs Typ

Input Common Mode Range Includes Positive Rail

Unity-Gain Stable for C-Load^TMUp to 10nF

Open-Loop Gain: 1 Million Typ

Guaranteed Specs with ±5V, ±15V Supplies

Guaranteed Matching Specifications

Standard Pinout: SO-8, SO-14 Package

■

In the design and testing of the LT1464/LT1465, particular

emphasis has been placed on optimizing performance in

thelowcostSO-8(dual)and14-leadSO(quad)packagefor

±15V and ±5V supplies. The input common mode range

includes the positive rail. Slew rate (0.5V/µs min) and gain

bandwidth product (650kHz min) are 100% tested. A full

set of matching specifications is also provided.

APPLICATIONS

■

Battery-Powered Systems

Photocurrent Amplifiers

Low Frequency, Micropower Active Filters
