OPA2277P Datasheet – Precision Operational Amplifier

The OPA2277P is a High Precision Operational Amplifier made by Burr Brown, supplied in a DIP 8 Pin Type package. Main ratings: ULTRA LOW OFFSET VOLTAGE 10mV; ULTRA LOW DRIFT ±0.1mV/°C; HIGH OPEN-LOOP GAIN 134dB; HIGH COMMON-MODE REJECTION 140dB. The absolute maximum ratings table on this page lists the 6 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the OPA2277P pinout, key specifications and maximum ratings, with the full datasheet PDF to preview below or download.

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 to ±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 ap- plies over the ±5V to ±15V supply range. High performance is maintained as the amplifiers swing to their specified limits. Because the initial offset voltage (±20mV max) is so low, user adjustment is usually not required. However, the single version (OPA277) provides external 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 freedom from interaction, even when overdriven or over- loaded.
