TSC214IYCT

Instrumentation, Op Amps, Buffer Amps Overview

The TSC214IYCT is a bidirectional, zero-drift current sense amplifier from STMicroelectronics. It features a fixed gain of 100 V/V and operates with a supply voltage range of 2.7 V to 26 V. The device supports a wide common mode voltage range from -0.3 V to +26 V, enabling high-side or low-side sensing regardless of the supply voltage. It utilizes a specific zero-drift architecture for high precision, offering an input offset voltage of ±60 µV maximum and a quiescent current of 100 µA typical. The component is housed in a compact SC-70-6 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'IYCT' corresponds to the required industrial temperature grade (-40°C to +125°C) and SC-70-6 packaging configuration. Confirm that the fixed 100 V/V gain aligns with system design requirements before procurement. Ensure compatibility with the intended shunt resistor values and reference voltage inputs for optimal performance.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed gain of 100 V/V is required for bidirectional current sensing applications. It is suitable for designs needing high precision with minimal offset drift over temperature. Consider the SC-70-6 package size constraints and the 100 µA quiescent current consumption against available power budgets.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TSC21x series of zero-drift current sense amplifiers. The series includes variants with different fixed gains (TSC210: 200 V/V, TSC211: 500 V/V, TSC212: 1000 V/V, TSC213: 50 V/V, TSC214: 100 V/V, TSC215: 75 V/V). All share the same core architecture and operating conditions but differ in internal gain settings.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Other members of the TSC21x family (TSC210, TSC211, TSC212, TSC213, TSC215) are pin-compatible alternatives if a different gain value is acceptable. Verify that the alternative gain meets the system's dynamic range and resolution requirements.
