OPA4241 OP Amp IC Chip

OPA4241(Single-Supply, MicroPOWER,OPERATIONAL AMPLIFIERS)

Introduction

The OPA241 series-OPA241/OPA2241/OPA4241 and OPA251 series are specifically designed for battery powered, portable applications. In addition to very low power consumption (25μA ), these amplifiers feature low offset voltage, rail-to-rail output swing, high common-mode rejection, and high open-loop gain.

The OPA241 series – OPA241/OPA2241/OPA4241 – optimizes operation at low power supply voltage, while the OPA251 series optimizes for high power supplies. Both can operate from either single(+2.7V to +36V) or dual supplies (±1.35V to ±18V). The input common-mode voltage range extends 200mV below the negative supply——ideal for single-supply applications.

They are unity-gain stable and can drive large capacitive loads. Special design considerations assure that these products are easy to use. High performance is maintained as the amplifiers swing to their specified limits. Because the initial offset voltage (±250µV max) is so low, user adjustment is usually not required. However, external trim pins are pro-vided for special applications (single versions only).

The OPA241 and OPA251 (single versions) are available in standard 8-pin DIP and SO-8 surface-mount packages.The 0PA2241 and 0PA2251 (dual versions) come in 8-pin DIP and SO-8 surface-mount packages. The OPA4241 and OPA4251 (quad versions) are available in 14-pin DIP and SO-14 surface-mount packages. All are fully specified from -40°C to +85°C and operate from -55°C to +125°C.
