The TLV2785IDR is a linear amplifier specially designed for applications requiring high accuracy and low distortion. It is a dual-channel wideband unity gain amplifier with a total supply voltage range of ±10 V to ±20 V. This amplifier is built with precision metal-film resistors, J-FET input transistors, and metal-oxide semiconductor (MOS) output transistors, and has a low distortion voltage noise specification of 0.0005%.

The TLV2785IDR can be used in a variety of applications, including instrumentation, OP amps, and buffer amps. When used as an instrumentation amplifier, it can accurately amplify small signals to a higher voltage level while preserving the signal integrity. The TLV2785IDR can also act as an operational amplifier, providing a stable, low-noise gain to the input signal from the differential input configuration. It can also be configured as a buffer amp, ensuring high dynamics and fast settling times for applications requiring analog-to-digital conversion and output current drive.

The TLV2785IDR is a low power device with a quiescent current of only 3.5 mA. It has a wide bandwidth of up to ±1 MHz and a wide common mode range of ±13 V. The extremely low distortion and noise levels make it ideal for use in instrumentation and audio test systems. The amplifier also features high input impedance inputs, providing more accurate measurements.

The TLV2785IDR’s volt-amp operation and feedback control features enable it to operate at a wide range of gain settings. Inputs include offset and gain control pins, allowing for precision adjustment. This amplifier also features current-limiting circuitry, allowing it to operate safely in unstable conditions, such as high input overloads.

The TLV2785IDR’s operating principle is a two-stage architecture with a common-source input stage, followed by a common-drain output stage. The input stage consists of a differential pair of J-FET transistors connected to the output of the gain and offset adjustment circuitry. The output stage provides wide bandwidth and high output current drive capabilities with a pair of MOSFETs. The combination of these two stages provides the high gain, low distortion, and low noise operation of the TLV2785IDR.
