TSC2012IDT

Instrumentation, Op Amps, Buffer Amps Overview

The TSC2012IDT is a high-voltage, precision bidirectional current sense amplifier from STMicroelectronics. It features a fixed gain of 100 V/V and supports a wide common mode voltage range from -20 V to +70 V, independent of the supply voltage. The device operates on a supply voltage between 2.7 V and 5.5 V and functions within an industrial temperature range of -40 °C to 125 °C. Key electrical specifications include a maximum offset voltage of ±200 µV, a maximum gain error of 0.3%, and a maximum offset drift of 5 µV/°C. It is housed in SO8 or MiniSO8 packages.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'IDT' against the official datasheet to confirm package type (SO8 or MiniSO8) and tape-and-reel configuration. Ensure the selected variant matches the required gain of 100 V/V and industrial temperature rating. Cross-reference part numbers with authorized distributors to confirm availability and authenticity before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the TSC2012IDT when a fixed gain of 100 V/V is required for amplifying small shunt voltages. This component is suitable for designs needing high common mode rejection and operation with supply voltages significantly lower than the sensed line voltage. Consider the input bias current impact on very low current measurements and ensure the output drive capability meets the load requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The TSC2012IDT belongs to the TSC201x family of high-voltage, precision, bidirectional current sense amplifiers manufactured by STMicroelectronics. This series includes variants with different fixed gains to accommodate various sensing requirements while maintaining consistent performance characteristics such as wide common mode voltage support and low offset voltage across the industrial temperature range.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The TSC2010IDT and TSC2011IDT are direct functional substitutes within the same product family. Selection depends on the required amplifier gain: use TSC2010IDT for 20 V/V or TSC2011IDT for 60 V/V. All three share identical pinouts, packages, and general electrical characteristics.
