I tested the TLC2272 chip and found that the rail-to-rail output is really good. [Copy link]

I received a plate of chips, brand new stock, the price is very good, only 0.2 cents each, it's awesome, after receiving the goods, I made a simple board test, input 800mV 1KHZ sine wave signal, power supply positive and negative 8V, the output can reach 16V, very satisfied. By the way, send a DEMO board for testing op amps, you can build the op amp test circuit yourself, it's very convenient, Jiali Chuang has a 5 yuan PCB proofing service, you can proof 5 pieces, and you can get 10 boards after proofing, which is enough for testing.
