TSV7721, TSV7722, TSV7723 Datasheet High bandwidth (22 MHz) low offset (200 V) 5 V op amp Features Gain bandwidth product 22 MHz, unity gain stable High accuracy input offset voltage: 50 V typ., 200 V max. Low input bias current: 2 pA typ. TSV7721 TSV7722 SOT23 -5 DFN8 2x2 mm Low input voltage noise density: 7 nV/Hz Wide supply voltage range: 1.8 V to 5.5 V Output rail-to-rail Input common-mode range includes low rail Automotive grade and shutdown versions available Benefits: TSV7723 TSV7722 High frequency signal conditioning MiniSO10 MiniSO8 Optimized accuracy for low-side current sensing Applications TSV7722 SO8 Low-side current measurement Photodiode amplifiers Automotive current measurement and sensor signal conditioning Strain gauges signal conditioning Description Maturity The TSV7721, TSV7722 and TSV7723 are single and dual 22 MHz-bandwidth unity- Package status link gain-stable amplifiers. The input offset voltage of 200 V max. (50 V typ.) at room temperature, optimized for common-mode close to ground makes the TSV772x ideal for low-side current measurements. 1 SOT23-5 The TSV772x can operate from 1.8 V to 5.5 V single supply and it is fully specified on TSV7721 a load of 47 pF, therefore allowing easy usage as A/D converters input buffer. 1 SOT23-5 The TSV772x series offers rail-to-rail output, excellent speed/power consumption 2 DFN8 ratio, and 22 MHz gain bandwidth product, while consuming just 1.7 mA at 5 V. 2 MiniSO8 The devices also feature an ultra-low input bias current that enables connection to TSV7722 2 SO8 photodiodes and other sensors where current is the key value to be measured. 2 MiniSO8 These features make the TSV772x series ideal for high-accuracy, high-bandwidth 2 SO8 sensor interfaces.
