DESCRIPTION

The OPA277 series precision op amps replace the industry

standard OP-177. They offer improved noise, wider output

voltage swing, and are twice as fast with half the quiescent

current. Features include ultra low offset voltage and drift, low

bias current, high common-mode rejection, and high power

supply rejection. Single, dual, and quad versions have identical

specifications for maximum design flexibility.

OPA277 series op amps operate from

±2V

±18V

supplies with

excellent performance. Unlike most op amps which are specified

at only one supply voltage, the OPA277 series is specified for

real-world applications; a single limit applies over the

±5V

±15V

supply range. High performance is maintained as the

amplifiers swing to their specified limits. Because the initial offset

voltage (±20µV max) is so low, user adjustment is usually not

required. However, the single version (OPA277) provides exter-

nal trim pins for special applications.

OPA277 op amps are easy to use and free from phase inversion

and overload problems found in some other op amps. They are

stable in unity gain and provide excellent dynamic behavior over

a wide range of load conditions. Dual and quad versions feature

completely independent circuitry for lowest crosstalk and free-

dom from interaction, even when overdriven or overloaded.

Single (OPA277) and dual (OPA2277) versions are available

in DIP-8, SO-8, and DFN-8 (4mm x 4mm) packages. The quad

(OPA4277) comes in DIP-14 and SO-14 surface-mount pack-

ages. All are fully specified from –40°C to +85°C and operate

from –55°C to +125°C.
