DESCRIPTION

The OPA129 is an ultra-low bias current monolithic

operational amplifier offered in an 8-pin PDIP and

SO-8 package. Using advanced geometry

dielectrically-isolated FET (Difet^®) inputs, this monolithic

amplifier achieves a high performance level.

V+

Difet fabrication eliminates isolation-junction leakage

current—the main contributor to input bias current with

conventional monolithic FETs. This reduces

input bias current by a factor of 10 to 100. Very low

input bias current can be achieved without resorting to

small-geometry FETs or CMOS designs which can

suffer from much larger offset voltage, voltage noise,

drift, and poor power-supply rejection.

Output

The OPA129 special pinout eliminates leakage current

that occurs with other op amps. Pins 1 and 4 have no

internal connection, allowing circuit board guard traces—

even with the surface-mount package version.

30kΩ

OPA129 is available in 8-pin DIP and SO packages,

V–

specified for operation from –40°C to +85°C.
