低功耗运放（<1mA）

获得AEC-Q100认证的 TSU111IY和 TSU112IY运算放大器均具有 超高精度和 超低功耗，其供电电压范围为1.5至5.5 V，可以由纽扣锂电池或稳定电压高效供电，适用于传感器信号调节、电池管理系统，以及无线和车载充电器 (OBC) 等低功耗汽车应用。

TSZ901是一款高精度零漂移运算放大器，专为需要卓越精度与稳定性的严苛应用而设计。在25 °C时具有5 μV的超低偏移电压，并在宽温度范围内保持极低漂移，确保精度始终如一。该器件支持轨到轨输入输出操作和低电源电压（2.5 V至5.5 V）运行，在5 V供电下仅消耗1.5 mA电流即可提供10 MHz的增益带宽积。

通过车规级AEC-Q100认证并支持扩展温度范围，是高精度信号调节、汽车电流检测和传感器信号调节的理想选择。

TSU111H是一款具有高精度、超低功耗和23 kHz增益带宽的 汽车级运算放大器。 
TSU111H采用SOT23-5封装， 适用于传感器信号调节、电池管理系统、板上充电器（OBC）和无线充电器。

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.

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.
