The TLC083AIN is an operational amplifier (op-amp) with a rail to rail input and output range for micro-power applications. It is available in three different versions: discrete DIP, DIP with an integrated filter capacitor, and a surface mount SOT23-6 or SMD type package. The device features a low-noise MOSFET preamplifier, an inverting input terminal, an output buffer stage and a temperature-compensated current source.

The TLC083AIN has two major application field. Firstly, it is widely applied as an analog building-block in various instruments and meters. In this field, the device can be used for ac/dc damping and linear amplification, switched capacitors, sample and hold, frequency sweep, and one-shot analog memory, etc. Besides, it is also used in the audio and communications measurement and process control systems. By using this single device, designs can easily achieve low-cost, low-power, and high-float accuracy with low-voltage operation from the ±1V to ±5.5V power supply.

The TLC083AIN consists of a MOSFET input stage, a three-stage high-gain differential amplifier, a compensation network, and a follower output-driver stage. The main active stages of the device are comprised of an N-channel MOSFET input stage and a P-channel MOSFET output buffer.MOSFET devices enable the improved rail-to-rail input and output performance of this device. The MOSFET devices offer higher input impedance, improved common-mode input range and higher slew rate. The slewing rate of the device is also improved due to the lowering of the device’s stability compensation network\'s corner frequency, resulting in improved slew rate.

The internal compensating resistor of the TLC083AIN reduces circuit start-up time and delivers improved stability with any load. It achieves a fast start-up by preventing the current from the P-channel of the output buffer from reverse flowing into the MOSFET input stage at the start-up. With low set-up time and improved load regulation, the TLC083AIN is a great choice for DC-coupled systems where the operational amplifier must maintain its optimum performance throughout the system\'s dynamic range.

Overall, the TLC083AIN is an ideal choice for applications requiring low-power and high-accuracy in a compact form factor. With its MOSFET-based preamplifier, high-slew rate and low-noise, the device is capable of delivering excellent performance under a variety of different conditions. With its small size, low-power operation and low-voltage operation, it can be used in a variety of applications.
