TSH113IPT

Instrumentation, Op Amps, Buffer Amps Overview

The TSH113IPT is a triple current feedback operational amplifier from STMicroelectronics, housed in a TSSOP-14 package. It features a high slew rate of 450V/µs and a bandwidth of 100MHz with a quiescent supply current of 3.2mA per operator. The device operates on ±2.5V to ±6V dual or 5V to 12V single supplies. Each channel includes a Standby function for power-down mode with high output impedance. It delivers low noise (3nV/√Hz) and very low distortion, capable of driving a 100Ω load.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'IPT' corresponds to the TSSOP-14 thin shrink outline package and tape & reel packing configuration as defined in the official ST ordering table. Confirm that the component meets the required industrial temperature range specifications (-40°C to +85°C) for your intended deployment environment before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple channels are required within a compact footprint. The TSH113 offers three independent amplifiers with dedicated standby controls, making it suitable for systems requiring selective channel activation. Ensure the application benefits from current feedback topology characteristics rather than voltage feedback alternatives.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TSH11x series of wideband low-noise operational amplifiers manufactured by STMicroelectronics. The series encompasses single (TSH110), dual (TSH112), triple (TSH113), and quad (TSH114) variants. The TSH113 specifically provides three operational amplifiers in a single package, sharing common electrical characteristics such as high slew rate and low noise profiles across the family.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible substitutes within the same family include the TSH113ID (SO-14 package) and TSH113IDT (SO-14 tape & reel). These parts share identical electrical specifications but differ in physical package dimensions and mounting style compared to the TSSOP-14 variant.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the Standby function operate on the TSH113?

Each of the three operators has a dedicated Standby pin. Driving the pin to a low voltage level activates a power-down mode characterized by high output impedance and reduced current consumption, while a high voltage level maintains active operation.

What is the maximum supply voltage for the TSH113IPT?

The absolute maximum supply voltage rating is 14V. For standard operation, the device supports dual supplies from ±2.5V to ±6V or a single supply from 5V to 12V.
