Product details

Quad CMOS op-amp for low-power signal chains

It delivers a gain-bandwidth product of 525 kHz with a 0.62 V/µs slew rate, drawing just 570 µA total supply current across all four channels.

The 900 µV maximum input offset voltage is typical for a CMOS general-purpose amplifier — acceptable for most DC-coupled conditioning but worth budgeting if you are amplifying sub-millivolt signals.

Package and mounting

The narrow SOIC body is a common layout across TI's quad op-amp portfolio, so a board designed for a TLC274 or an LM324 in SOIC-14 will accept this part with no footprint change.

Frequently asked questions

Can TLC27M4ACD replace LM324?

The TLC27M4ACD is a CMOS quad op-amp with a 525 kHz GBW and 0.7 pA input bias, while the LM324 is a bipolar design with roughly 1 MHz GBW and 100 nA input bias. The TLC27M4ACD offers much lower input bias current and lower supply current (570 µA vs ~1.4 mA for the LM324), but its output swing is not rail-to-rail and its slew rate is lower. In a pin-compatible SOIC-14 footprint the TLC27M4ACD can drop in for many low-speed, high-impedance applications, but check the offset and output swing against your signal range.

What is the difference between TLC27M4ACD and TLC27M4BCD?

The A and B suffixes denote different input offset voltage grades. The TLC27M4ACD specifies a maximum input offset of 900 µV. The TLC27M4BCD typically grades to a tighter limit (often 500 µV max, though not in this ledger). If your design requires lower DC offset, the B-grade variant is the tighter bin; for general-purpose use the A-grade is sufficient.
