The LT1999CMS is a single, wide-range voltage-feedback amplifier ideal for precision measurement and control applications. It features high slew rate, low-noise, low-distortion, and ultra-high common-mode rejection ratios. The LT1999CMS8-20F#TRPBF is a fully-differential input/output amplifier optimized for the latest consumer audio products requiring the highest fidelity and fidelity.

Application Field

The LT1999CMS8-20F#TRPBF makes an ideal choice for applications requiring precision precision measurements or controls, particularly in consumer electronics, medical, industrial and automotive systems. Its high slew rate and wide bandwidth enable high-accuracy voltage measurements over a wide range of frequencies with exceptional signal-to-noise performance. It can also be used in high-impedance signal acquisition and instrumentation, providing common-mode rejection ratios of up to -90dB. It can also be used as an active gain-adjustable buffer or differential line receiver. In addition, its wide input/output common-mode range allows it to be used in single-supply systems.

Working Principle

The LT1999CMS8-20F#TRPBF is based on a wide-range voltage-feedback topology, which provides low-noise and high-impedance performance with very low distortion. The amplifier works by providing a constant voltage gain from the input to the output. This gain is proportional to the value of the feedback resistor and is controlled by the voltage at the reference pin. The output response of the amplifier is then adjusted by controlling this reference voltage. This amplifier can achieve exceptionally wide bandwidths and high slew rates when used with low-noise feedback resistors, resulting in excellent dynamic range and fast transient responses.

The LT1999CMS8-20F#TRPBF also features an internally-programmable common-mode rejection ratio (CMRR) of up to -90dB. This CMRR ensures that noise interference from adjacent differential-mode signals is rejected and provides higher performance in noisy or RF-hostile environments. The amplifier also features a wide common-mode input/output range, which allows it to be used in a single-supply system with up to ±2V of common-mode input/output range.

The LT1999CMS8-20F#TRPBF also features rail-to-rail input and output levels, allowing it to be easily used in applications where the input or output swing is very close to one of the power supply rails. This ensures that the amplifier will not saturate and the full range of the input signal can be used. The wide bandwidth and fast slew rate of the amplifier also make it ideal for applications requiring high frequency signals with low distortion.

The LT1999CMS8-20F#TRPBF is an ideal choice for precision measurement and control applications requiring high accuracy, low distortion, and wide frequency range. Its high slew rate and wide bandwidth make it ideal for applications needing fast transient response and high dynamic range, while its very low-noise and high common-mode rejection ensure that the amplifier performs well in noisy or RF-hostile environments. The wide common-mode input/output range also allows it to be used in single-supply systems with up to 2V of common-mode range, while its rail-to-rail input and output levels ensure that it will not saturate when used with these same supply voltages.
