DESCRIPTIONThe 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.
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.
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.
OPA129 is available in 8-pin DIP and SO packages,
specified for operation from –40 °C to +85°C.
