Channel Automotive Description
TSV782IQ2T 2 DFN8 TSV782IST 2 MiniSO8 The TSV782 is a 30 MHz-bandwidth unity-gain-stable amplifier. The rail-to-rail input stage and the slew rate of 20 V/µs make the TSV782 ideal for low-side current TSV782IDT 2 SO8 measurement. TSV782IYST 2 • MiniSO8 The TSV78x can operate from 2.0 V to 5.5 V single supply and it is fully specified on TSV782IYDT 2 • SO8 a load of 47 pF, therefore allowing easy usage as A/D converters input buffer. The TSV78x series offers rail-to-rail input and output, excellent speed/power consumption ratio, and 30 MHz gain bandwidth product, while consuming just 3.3 mA at 5 V.
