Description
The MP5121 (single), MP5221 (dual), and MP5421 (quad) are high-speed, high-voltage rail-to-rail input-output amplifiers for use as voltage reference buffers in Thin Film Transistor Liquid Crystal Displays (TFT-LCDs). The MP5121 family provides excellent overall performance and versatility. The 20MHz -3dB bandwidth and 45V/μs slew rate make these amplifier suitable for many portable applications. The MP5121, MP5221, and MP5421 are designed to operate at supply voltages as low as 3.2V and up to 20V at 1.6mA of supply current per amplifier. The MP5121 family has true single supply capability. The input can swing 0.5V below the negative rail and 0.5V above the positive rail. The output can swing within 100mV of each rail. The MP5421 quad channel is available in the space-saving 14-pin TSSOP package. The MP5221 Dual channel is available in the 8-pin MSOP package and the MP5121 single channel is available in 5-pin TSOT package. All feature a standard operational amplifier pin out.

OPERATIONAL AMPLIFIER BASICS, TYPES, AND ADVANTAGESARTICLEAn operational amplifier (op amp) is an analog circuit block that takes a differential voltage input and produces a single-ended voltage output. Op amps usually have three terminals: two high-impedance inputs and a low-impedance output port. The inverting input is denoted with a minus (-) sign, and the non-inverting input uses a positive (+) sign. Operational amplifiers work to amplify the voltag...

VOLTAGE REGULATOR TYPES AND WORKING PRINCIPLESARTICLEA voltage regulator is a circuit that creates and maintains a fixed output voltage, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from a power supply within a range that is compatible with the other electrical components. While voltage regulators are most commonly used for DC/DC power conversion, some can perform AC/AC or AC/DC power c...
