The STMicroelectronics TSC2011IDT is a single-channel current sense amplifier in an 8-SOIC package, designed to monitor current by sensing the voltage drop across a shunt resistor. The input offset voltage is 500 µV, and the supply current is 1.6 mA.
750 kHz bandwidth and 8 V/µs slew rate — transient tracking margin
The 750 kHz -3 dB bandwidth and 8 V/µs slew rate mean the TSC2011IDT can reproduce current waveforms from a 100 kHz switching regulator with enough fidelity for closed-loop control or overcurrent detection. The 350 µA input bias current is a consequence of the internal sense resistor topology — it flows through the shunt, so the shunt value and power dissipation need to be checked against the bias current at the maximum differential voltage. The 36 mA output drive per channel is sufficient to drive the ADC input of a typical MCU or a comparator directly.
For a current-sense amplifier in an 8-SOIC, this part is still a standard production item, so the supply channel is stable through franchised distribution and independent stock. The closest functional peer in the same family is the TSC200IDT, which offers a 1 MHz bandwidth and 7 V/µs slew rate with a 500 nA input bias current — a lower-bias alternative if the shunt dissipation is a concern, but the TSC2011IDT's higher slew rate gives better edge fidelity for fast transient capture.
