| FFF Compatibility | The pin configuration (NC, IN+, IN-, GND, VCC, VREF2, VREF1, OUT) and package footprint are identical to the target TSSOP-8 package.Both parts utilize the standard 8-TSSOP package with identical mounting and physical dimensions.Matches the target gain of 20 V/V, features enhanced PWM rejection, and operates over the same 2.7 V to 5.5 V supply range with superior voltage ratings. | Features the exact same TSSOP-8 pinout and physical package mounting pattern.Identical TSSOP-8 dimensions and physical form factor.While it matches the 20 V/V gain, it has a slightly higher maximum input offset voltage (±150 µV vs ±25 µV typical for the INA240) which may impact low-current measurement precision. | ||
 AI Summary | INA240A1QPWRQ1 by Texas Instruments: Current Sense Amplifier 1 Circuit 8-TSSOP. | The TSC240A1IYPT is STMicroelectronics' direct drop-in alternative specifically designed as a pin-compatible replacement for the INA240A1 series. It offers enhanced PWM rejection, a matching 20 V/V gain, and extends the input common-mode safety ceiling to 100 V. This makes it an exceptionally safe and robust second-source option without requiring any schematic or PCB modifications.
| The TSC2020IYPT is a high-precision, bidirectional current-sense amplifier from STMicroelectronics that serves as a pin-compatible alternative. It matches the 20 V/V gain option and provides an expanded 100 V common-mode ceiling, though it exhibits a slightly relaxed input offset spec compared to the premium INA240. It is suitable for applications where the utmost extreme low-offset performance is not critical.
