As portable electrical equipment becomes more commonplace, electrical applications use a single supply voltage of 5 V or less more frequently.
One battery cell’s voltage can be used as the supply voltage for portable devices (1.5 V). To have a viable dynamic range, reduced supply voltage systems must utilise the entire power supply span. Rail-to-rail amplifiers are operational amplifiers that condition signals using the entire range between the negative and positive source voltage.
The useable span has a significant impact on a number of metrics, including dynamic range, noise susceptibility, and signal-to-noise ratio (SNR). The positive or negative supply rails are frequently used to link signal sources. Operational amplifiers must be able to match both signal sources with rail-to-rail input capability.
Input and output voltage fluctuations in rail-to-rail amplifiers are very close to or almost equal to the supply voltage value. The main advantage of this kind of op-amp is that it can widen the signal’s voltage range. However, because the output current is often low, it cannot always provide rail-to-rail operation when the current is large.
The Global rail-to-rail op amp market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The TSV782 is a 30MHz-bandwidth unity-gain-stable amplifier. The rail-to-rail input stage and slew rate of 20 V/µs make the TSV782 ideal for low-side current measurement.
The device also features an ultra-low input bias current that enables connection to photodiodes and other sensors where current is the key value to be measured.
