Product details

Single rail-to-rail op-amp with 80 mA output drive

It delivers a 4 MHz gain-bandwidth product with a 1.3 V/µs slew rate, and its rail-to-rail output stage swings within millivolts of both supply rails — critical for single-supply designs running from 2.7 V up to 12 V. The -40 to 125 °C operating range qualifies it for industrial sensor interfaces, automotive cabin electronics, and outdoor telecom line cards.

Lifecycle and sourcing — active, ROHS3, available to order

Package and temperature grade — 8-SOIC, -40 to 125 °C

The 8-SOIC package (0.154" body width, 3.90 mm) is a standard footprint shared with countless op-amps, ADCs, and interface ICs — no board respin needed if swapping from a similar single-channel op-amp.

Frequently asked questions

What is the equivalent or replacement for TS921IDT?

The TS921ID (Tube package) is electrically identical — same 4 MHz GBW, 1.3 V/µs slew rate, rail-to-rail output, and 80 mA drive. The only difference is the delivery format: Tape & Reel (TS921IDT) vs Tube (TS921ID).

Is TS921IDT RoHS compliant?

Yes, the TS921IDT is ROHS3 compliant.

Can TS921IDT replace a standard op-amp like LM358?

The TS921IDT is a single-channel device with a 2.7–12 V supply range, rail-to-rail output, and 80 mA output drive. The LM358 is a dual-channel op-amp with a wider supply range (3–32 V) and lower output current. The TS921IDT can replace one channel of an LM358 in a low-voltage, single-supply design where rail-to-rail swing and higher output drive are needed, but the pinout and supply limits must be checked.
