STMicroelectronics' TSU114 quad channel version operational amplifiers offer an ultra-low power consumption per channel of 900 nA typical and 1.2 µV maximum when supplied by 3.3 V. Combined with a supply voltage range of 1.5 V to 5.5 V, these features allow the TSU11x to be efficiently supplied by a coin type lithium battery or a regulated voltage in low-power applications. The high accuracy of 150 µV max. and 11.5 kHz gain bandwidth make the TSU11x ideal for sensor signal conditioning, battery supplies, and portable applications.
