Precision High Voltage Op-amps

New rail-to-rail inputs and outputs, 36 V, 6 MHz op-amps

The TSB514 is a 6 MHz bandwidth amplifier featuring rail-to-rail input and output, which are guaranteed to operate from 2.7 to 36 V single supply as well as from ± 1.35 V to ± 18 V dual supplies.

This amplifier has the advantage of offering a large span of supply voltage, a wide bandwidth and 4 outputs.

The combination of wide bandwidth, slew rate, low noise, rail-to-rail capability makes the TSB514 useful in a wide variety of applications such as: filters, power supply and motor control, actuator driving and resistive transducers.

Automotive grade versions are also avaiable.

TSB series: 36 V op amps for automotive and industrial applications

 

In addition to an excellent speed / power ratio, our 36 V TSB series of op amps offer outstanding power density and high tolerance to ESD combined with low-power consumption:

•       The stability and robustness of our 380 µA / 2.5 MHz TSB57 operational amplifiers make them an ideal solution for a wide voltage range of applications. Available in single- (TSB571) and dual-channel (TSB572) versions.

•       Our 100 µA / 560 kHz TSB61 operational amplifiers operate over a wide temperature range from -40 °C to 125°C, ideal for industrial and automotive applications. Available in single- (TSB611) and dual-channel (TSB612) versions.

•       The combination of wide bandwidth, slew rate, low noise, rail-to-rail capability and precision makes our 1.8 mA / 6 MHz TSB711 (single-channel) and TSB712 (dual-channel) op amps useful in a wide variety of applications including filters, power supplies and motor control, actuator driving, Hall effect sensors and resistive transducers. Also available in 22 MHz versions: TSB7191 (single-channel) and TSB7192 (dual-channel)

TSB582: High output current (200mA) 36V BiCMOS dual operational amplifier

Available in space saving packages with minimized thermal resistance due to exposed pads, the TSB582 is a dual operational amplifier with embedded thermal shutdown and output current limiter for both industrial and automotive applications.

In closed-loop motor control systems a preferred way to read out the shaft’s angular position is the rotary resolver. Resolvers can be found in various applications, from light industrial to heavy duty, such as: servo motor feedback, oil and gas production, jet engine fuel systems, aircraft flight surface actuators, communication position systems, steering wheels or vehicle control systems.

Since the primary winding is typically powered through a rotary transformer, no brushes or rings are needed. This increases the overall reliability and robustness of the resolver and makes it perfectly suitable for harsh environments with varying temperature and in oily, dusty, or humid surroundings.

The TSB582 was originally designed to manage the power amplification to pilot the primary winding of a resolver device. Thanks to a wide supply voltage range (4 to 36V) the TSB582 is also an excellent fit for power demanding applications like: AC and DC power sources, valve drivers, line drivers, LED drivers and servo drivers.
