Quad op-amp with 525 kHz GBW and 0.62 V/µs slew rate
The TLC27M4CDR is a quad general-purpose operational amplifier from Texas Instruments' LinCMOS™ series, offering a gain bandwidth product of 525 kHz and a slew rate of 0.62 V/µs. It draws 570 µA total supply current across all four channels, making it suitable for battery-powered or power-sensitive analog signal conditioning where low quiescent draw is a priority.
Input bias and offset — what they mean for sensor front-ends
Input bias current is 0.7 pA typical, which is negligible for high-impedance sources like photodiode or pH probe amplifiers — the voltage error across a 10 MΩ source is under 7 µV. Input offset voltage is 1.1 mV typical, a figure that sets the DC accuracy floor for the gain stage; for a gain of 100, the output offset contribution is 110 mV before trimming.
Supply range and output drive
Operates from a single supply span of 3 V to 16 V, covering common 3.3 V, 5 V, and 12 V rails without needing a split supply. Each output can source or sink 30 mA, enough to drive an ADC input, a small relay coil, or a 50 Ω back-terminated line in short runs.
Temperature grade and environment
Rated for 0°C to 70°C commercial temperature range — this is the indoor, bench, or office-environment band; not specified for automotive or extended industrial use.
Sourcing and lifecycle
Supplied in 14-SOIC surface-mount package, available in Tape & Reel or Cut Tape options — quoted to order against your BOM quantity; availability and current pricing confirmed at RFQ.
