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. 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).
The TS27L4 series are low-cost, low-power quad operational amplifiers using ST silicon gate CMOS process. They feature very low power consumption (10 pA/op), unity gain stability, and excellent phase margin on capacitive loads.
These devices offer three power consumption options within the series: TS27L4 for very low power (10 pA/op), TS27M4 for low power (150 pA/op), and TS274 for standard power (1 mA/amp). The amplifiers provide high input impedance, extremely low input currents, and output voltage swing to ground.
