350 kHz GBW, 0.11 V/µs slew — a micropower signal-conditioning quad
The Texas Instruments LPC660IMX/NOPB is a CMOS quad operational amplifier designed for low-power, precision signal conditioning in multi-channel sensor interfaces and battery-operated instrumentation. Its 350 kHz gain-bandwidth product and 0.11 V/µs slew rate place it firmly in the low-frequency domain — think thermocouple amplifiers, photodiode transimpedance stages, and 4-20 mA loop transmitters — not high-speed ADC drivers or video lines. The rail-to-rail output stage (Push-Pull, Rail-to-Rail) allows maximum dynamic range in single-supply designs down to 4.75 V and up to 15.5 V.
160 µA total supply — four amplifiers, one power budget
At 160 µA total for all four channels (40 µA per amplifier), this part is a strong fit for multi-channel data-acquisition systems where every microamp counts. The 0.002 pA input bias current (Current - Input Bias) means you can connect high-impedance sources — pH probes, pyroelectric sensors, or high-value feedback resistors — without adding a JFET buffer or seeing significant offset drift from bias current. The 1 mV input offset voltage (Voltage - Input Offset) is adequate for 8- to 10-bit accuracy in the signal chain; for higher precision, a chopper-stabilized amplifier would be needed.
