STMicroelectronics’ automotive-qualified op amps ship excessive accuracy and stability over a large (-40°C to 175°C) temperature vary.
STMicroelectronics’ TSZ181H1 and twin TSZ182H1 automotive-qualified operational amplifiers (op amps) ship excessive accuracy and stability over a large (-40°C to 175°C) temperature vary. The excessive most working temperature encourages use in harsh environments and in functions with lengthy mission profiles.
The op amps have very low enter offset voltage, typical 3.5µV at 25°Cm, and enter bias present, typical 30pA at 25°C. The parameters show minimal drift over temperature, with most enter offset voltage specified as 70µV at 25°C and 100µV over the total temperature vary. The utmost specified enter bias present is 200pA at 25°C and 225pA over the total vary.
With their broad operating-temperature vary, the TSZ181H1 and TSZ182H1 stand up to harsh environments in industrial in addition to automotive functions. At decrease die temperature, they will function for an prolonged lifetime in functions that require a protracted mission-profile ICs. The gadgets are AEC-Q100 certified and have 4kV HBM ESD tolerance.
The TSZ181H1 and TSZ182H1 ship excellent efficiency in high-accuracy, high-bandwidth sensor interfaces. They can be utilized for precision sign conditioning with out calibration, thereby simplifying end-product manufacturing whereas making certain greater accuracy than typical op amps. The gain-bandwidth of 3MHz and working present of simply 1mA at 5V present a superior speed-to-power ratio. Designed for a large energy provide voltage vary, from 2.2V to five.5V, each gadgets have rail-to-rail enter and output to maximise usable dynamic vary.
Each op amps are in manufacturing now and accessible in a selection of SOT23-5 or SO8 packages.
