STMicroelectronics TS3121A
The TS3121, TS3121A and TS3121P single comparators permit high-speed response time at low power consumption over a supply voltage specified from 1.7 to 5.5 V. These devices operate over a wide temperature range from -40 °C to +125 °C making them ideal for industrial and automotive applications with the associated qualification. It can thus reduce the overall cost of the PCB.| Part No. | TS3121A |
