The LT1637CDD#PBF is a dual-differential monolithic operational amplifier with high common-mode input voltage range and low-power supply current. It is designed for applications such as instrumentation, voltage-controlled amplifiers, headphone drivers, and power amplifiers.

General Description:

The LT1637CDD#PBF is a dual-differential monolithic operational amplifier with high common-mode input voltage range and low-power supply current. It is designed to provide improved performances from popular devices, like the LT1740 and LT750, with only half the required power supply current. The input voltage range of the LT1637CDD#PBF can reach as high as ± 40V. The high common-mode input range and low power supply current reduces the amount of heat dissipated in op amps and audio amplifiers. This makes the LT1637CDD#PBF ideal for applications such as instrumentation, voltage-controlled amplifiers, headphone drivers, and power amplifiers.

Working Principle:

The LT1637CDD#PBF is a dual-differential monolithic operational amplifier with high common-mode input voltage range and low-power supply current. It is designed to provide improved performances from popular devices, like the LT1740 and LT750, with only half the required power supply current. The LT1637CDD#PBF operates on a single +5V power supply and can also operate on a dual ± 5V power supply. The op amp consists of two amplifier channels connected in parallel between the input and output. Due to the differentially coupled amplifier design, the LT1637CDD#PBF has a wide input voltage range from ±40V. The wide input voltage range makes it ideal for high common-mode voltages and low power supply current applications.

The LT1637CDD#PBF is designed for single power supply operation, with an output voltage range from 0V to 6V and a differential input voltage range from ±50V. The LT1637CDD#PBF is designed to provide improved performances from popular devices, like the LT1740 and LT750. It has a low supply current of 2.6mA/amplifier, a high common-mode range of ±40V, and a high output current capability of 1.7A/channel. The op amp is designed to operate from a wide operating temperature range from -40°C to +125°C.
