MP5421 3.2-20V Single-Supply Op Amps TSOT-5
The MPS MP5421 is a Single-Supply Op Amps. It operates from a 3.2 V to 20 V input. It is supplied in a TSOT-5 package.
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).

Design Notes
- Check the input common-mode range against the actual signal, especially in single-supply rails where ground-referenced signals sit at the edge.
- Capacitive load drives stability; add series isolation when driving cables or ADC inputs directly.
- Offset voltage and its drift, not gain bandwidth, usually set the achievable accuracy in DC instrumentation.
- Decouple at the pin with the smallest package capacitor that meets the transient requirement, returned to a local ground.
