TSU11 series: nano-power (900 nA), high-accuracy (150 µV) op amps
The TSU111 (single-version channel) TSU112 (dual-version channel) and TSU114 (quad-version channel) operational amplifiers offer an ultra-low power consumption per channel of 900 nA (typical) and 1.2 µA (maximum) when supplied by 3.3 V.
Combined with a supply voltage range of 1.5 to 5.5 V, these features allow the TSU11 series to be efficiently supplied by a coin-type Lithium battery or a regulated voltage in low-power applications.
The high accuracy of 150 µV (maximum) max. and 11.5 kHz gain bandwidth make these op amps ideal for sensor signal conditioning, battery-supplied or energy-harvesting applications.
TSZ12 series: ultra precision and low-power op amp for IoT applications
ST’s zero-drift op amps ideal choice for sensor and control interfaces in a wide range of battery-powered IoT applications.
The devices operate from 1.8V to 5.5V, with quiescent current below 40μA at 5V, gain-bandwidth product of 400kHz, and ultra-low input bias current.
- The single-channel TSZ121 is pin- and package-compatible with comparable devices from other manufacturers.
- The dual-channel TSZ122 offers popular MiniSO-8 and SO-8 packages plus the option of a miniature 2mm x 2mm DFN8.
- The TSZ124 quad op amp in TSSOP-14 and 3mm x 3mm QFN16
The devices provide the industry’s broadest choice of zero-drift op amps.
