TSH113ID

Instrumentation, Op Amps, Buffer Amps Overview

The TSH113ID is a triple current feedback operational amplifier from STMicroelectronics, designed for high-speed signal processing. It features a typical slew rate of 450V/µs and a bandwidth of 100MHz with a low quiescent supply current of 3.2mA per operator. The device operates on dual supplies from ±2.5V to ±6V or single supplies from 5V to 12V. Each channel includes a Standby function that reduces power consumption significantly while maintaining high output impedance. It offers low noise performance at 3nV/√Hz and can drive a 100Ω load with a minimum swing of 9V under a 12V supply.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package variant (SO-14 or TSSOP14) required for your design, as the base part number may be followed by suffixes indicating packing method such as tube or tape & reel. Confirm the operating temperature range meets system requirements, typically -40°C to +85°C. Ensure the standby logic levels align with your control interface voltages. Check for any recent product lifecycle notifications regarding availability or obsolescence status directly from the manufacturer.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple channels are needed in a compact form factor without sacrificing speed. The current feedback topology provides faster settling times compared to voltage feedback amplifiers. Consider the standby feature if power management during idle periods is critical. Ensure the application does not require rail-to-rail output swing, as this device has limited output voltage ranges relative to the supply rails.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TSH11x family of wideband low noise operational amplifiers, which also includes single (TSH110), dual (TSH112), and quad (TSH114) variants. The family shares similar electrical characteristics but differs in channel count and package options. The TSH113 specifically targets applications requiring three independent high-speed channels with individual power-down capabilities.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include TSH113IPT (TSSOP14 package). Other series like THS4011 offer similar high-speed performance but differ in topology and pinout. Verify compatibility before swapping.
