STMicroelectronics TS27L4
The TS27L4 series 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.| Part No. | TS27L4 |

FEATURES
● Very low power consumption: 10 µA/op● Output voltage can swing to ground
● Excellent phase margin on capacitive loads
● Unity gain stable
● Two input offset voltage selections
DESCRIPTION
Three power consumptions are available enabling the best consumption-speed ratio: ICC = 10 µA/amp: TS27L4 (very low power), ICC = 150 µA/amp: TS27M4 (low power), ICC = 1 mA/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 (see Figure 4).
