These devices are low cost, low power quad operational amplifiers designed to operate with single or dual supplies. These operational amplifiers use the ST silicon gate CMOS process allowing an excellent consumption-speed ratio. These series are ideally suited for low consumption applications. Three power consumptions are available allowing to have always the best consumption-speed ratio: K ICC = 10µA/amp.: TS27L4 (very low power) K ICC = 150µA/amp.: TS27M4 (low power) K ICC = 1mA/amp.: TS274 (standard) These CMOS amplifiers offer very high input impedance and extremely low input currents. The major advantage versus JFET devices is the very low input current drift with temperature.
The TS27M4C series are precision low‑power CMOS quad operational amplifiers designed for single‑ or dual‑supply operation. They feature ultra‑low supply current (150 pA per amplifier) and excellent phase margin on capacitive loads, making them suitable for battery‑powered and low‑consumption applications.
The datasheet lists absolute maximum ratings, typical electrical characteristics such as input offset voltage, gain‑bandwidth product, and phase margin, as well as mechanical dimensions for DIP, SO, and TSSOP packages. Package options include 14‑pin plastic DIP, plastic micro‑package (SO), and thin‑shrink small‑outline (TSSOP).
