LMV324BG-13

The LMV324BG-13 is a Texas Instruments quad operational amplifier in the LMV324 family. It contains four rail-to-rail input/output op-amps in a single 14‑pin package, designed for low‑voltage, single‑supply use.
Key points:
- Supply range: typically 2.7–5.5 V (single supply)
- Rail-to-rail input and output
- Low quiescent current, suitable for battery-powered and compact designs
- Four op-amps per device; common applications include buffers, filters, and sensor amplification
- The “BG-13” suffix denotes a specific packaging/temperature variant (lead‑free, RoHS-compliant) in TI’s line
For exact pinout, electrical specs, and guaranteed performance (temperature range, GBW, slew rate, input bias, etc.), consult the TI LMV324BG-13 datasheet.

Key features of LMV324BG-13:
- Quad low-voltage operational amplifiers in one package
- Single-supply operation from 2.7 V to 5.5 V
- Rail-to-rail input and rail-to-rail output
- Input common-mode range includes the negative rail
- Output can swing to ground and close to the supply rail under light loads
- Unity-gain stable (suitable for buffering and filtering)
- Low quiescent current per amplifier
- Low input bias and offset voltages
- Internally compensated for stable closed-loop performance
- Wide operating temperature range (typical industrial -40°C to 125°C)
Ideal for battery-powered, portable, and sensor-interface applications where multiple amplifiers are needed in a small footprint.

- Pin count: 14 pins (DIP/SOIC/TSSOP variants).
- Function: Quad operational amplifier — four independent, rail-to-rail input/output op-amps in one package for single-supply, low-power signal conditioning (supply typically 1.8–5.5 V).
