Product details
Overview
LMV825AIPT from STMicroelectronics is a quad-channel, rail-to-rail output operational amplifier with integrated shutdown control, designed for precision signal conditioning in automotive and battery-powered systems. It delivers 5.5 MHz gain bandwidth, 0.8 mV max input offset voltage at 25°C, 400 µA per channel supply current at 5 V, and operates across –40°C to +125°C. It is used in automotive sensor front-ends requiring low-power, high-accuracy amplification with fast enable/disable control.
For engineers reviewing the LMV825AIPT datasheet, LMV825AIPT pinout, LMV825AIPT application, or LMV825AIPT equivalent, key selection criteria include shutdown current (≤50 nA), rail-to-rail output swing (≤150 mV from rails), input offset drift (1 µV/°C), and guaranteed performance over extended temperature range - all critical for automotive signal chains and portable medical sensors.
Technical Context
The LMV825AIPT implements a CMOS input stage with rail-to-rail output stage, enabling operation down to 2.5 V supply while maintaining 70–90 dB common-mode and supply voltage rejection. Its shutdown logic uses a dedicated SHDN pin referenced to VCC−, with VIH ≥ VCC−0.5 V and VIL ≤ 0.5 V, ensuring robust disable/enable sequencing in noisy automotive environments.
It features a unity-gain stable architecture with 60° phase margin and 10 dB gain margin, supporting stable operation with capacitive loads up to 200 pF. The amplifier's 1.4–1.9 V/µs slew rate and 13–16 nV/√Hz input voltage noise at 10 kHz support high-fidelity active filtering and sensor buffering without oscillation or distortion.
Key Specifications

|---|---|
| Gain Bandwidth Product | 5.5 MHz - enables stable unity-gain buffer or 2nd-order active filter design up to ~500 kHz. |
| Input Offset Voltage (max) | 0.8 mV at 25°C - reduces DC error in precision instrumentation without calibration. |
| Supply Current (per channel) | 400 µA max at 5 V - extends battery life in multi-channel portable devices. |

Pinout & Package
TSSOP-16 package (3.0 mm × 4.4 mm, 0.65 mm pitch) with exposed thermal pad (connected to VCC− or left floating per datasheet).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN_A) | Channel A shutdown control | Active-low logic input; pulls amplifier A into high-Z output state when ≤0.5 V. |
| 2 (IN−_A) | Inverting input, Channel A | Accepts input common-mode voltage from VCC− − 0.2 V to VCC+ − 1 V - includes ground reference. |
| 3 (IN+_A) | Non-inverting input, Channel A | Matches IN−_A specs; supports single-ended or differential sensing with matched bias currents. |
| 4 (VCC−) | Negative supply rail | Ground reference for single-supply operation; SHDN pin is referenced to this node. |
| 5 (OUT_A) | Amplifier A output | Rail-to-rail capable; sinks/supplies ≥25 mA at 5 V, remains stable with 200 pF load. |
| 6 (OUT_B) | Amplifier B output | Electrically identical to OUT_A; enables dual-channel signal path in same footprint. |
| 7 (IN+_B) | Non-inverting input, Channel B | Independent input with same CMVR and offset specs as Channel A. |
| 8 (IN−_B) | Inverting input, Channel B | Matched to Channel A for common-mode rejection in differential configurations. |
| 9 (VCC+) | Positive supply rail | Accepts 2.5–5.5 V; internal regulation ensures consistent biasing across voltage range. |
| 10 (IN−_C) | Inverting input, Channel C | Third independent op-amp input; supports triple-sensor conditioning or cascaded filtering. |
| 11 (IN+_C) | Non-inverting input, Channel C | Paired with IN−_C; enables precision gain stages without external resistor matching. |
| 12 (OUT_C) | Amplifier C output | Delivers same AC/DC performance as OUT_A/B; supports multi-stage analog signal chain. |
| 13 (SHDN_C) | Channel C shutdown control | Independent shutdown pin - allows selective power gating of individual channels. |
| 14 (OUT_D) | Amplifier D output | Fourth output; completes quad configuration for complex sensor fusion or redundancy schemes. |
| 15 (IN+_D) | Non-inverting input, Channel D | Enables full four-channel parallel processing, e.g., for multi-axis IMU or ECG lead amplification. |
| 16 (IN−_D) | Inverting input, Channel D | Final input pair; maintains matched layout and parasitic characteristics across all four channels. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV854IST | Lower supply current (180 µA/ch), but reduced GBP (1.3 MHz) and no shutdown function. | Suitable for ultra-low-power always-on monitoring where bandwidth <1 MHz suffices. | Select when minimizing average current outweighs need for fast settling or channel-level power control. |
| LMV844QDGKR | Automotive-qualified quad op-amp with 10 MHz GBP and 1.5 V/µs slew rate, but higher ICC (1.2 mA/ch) and no shutdown. | Better for high-speed signal acquisition (e.g., motor current sensing), not low-power sleep modes. | Choose when bandwidth and slew rate are prioritized over shutdown capability and quiescent current. |
Compared with TSV854IST and LMV844QDGKR, the LMV825AIPT uniquely balances 5.5 MHz bandwidth, 400 µA/ch consumption, per-channel shutdown, and AEC-Q100 qualification - making it optimal for automotive and portable systems requiring both precision and intelligent power management.

FAQ
What is the maximum capacitive load the LMV825AIPT can drive stably?
The LMV825AIPT maintains stability with up to 200 pF capacitive load without external compensation, as verified in Figure 10 and Figure 11 of the datasheet. This eliminates the need for series isolation resistors when driving ADC input capacitors or long PCB traces, simplifying layout and preserving signal integrity in high-resolution data acquisition systems.
How does the shutdown function affect output state and leakage?
When the SHDN pin is pulled low (≤0.5 V), the amplifier output enters high-impedance state with ≤1 nA leakage current over –40°C to +125°C, per Table 5–9. This prevents loading of downstream circuitry and enables safe multiplexing or shared bus architectures without signal contention.
Is the LMV825AIPT pin-compatible with other quad op-amps in TSSOP-16?
No - the LMV825AIPT uses a proprietary pinout with dedicated shutdown pins for Channels A and C (Pins 1 and 13), differing from standard quad op-amp layouts like the LM324 or TLV2464. Layout redesign is required when substituting; refer to Figure 1 in the datasheet for exact top-view mapping.
What decoupling is recommended for optimal noise performance?
STMicroelectronics recommends placing a 10 nF ceramic capacitor as close as possible to each VCC+ and VCC− pair (Pins 9 and 4), per Section 4.5. For multi-channel operation, separate 10 nF caps per supply pin pair reduce crosstalk and improve PSRR above 100 kHz, especially critical in mixed-signal automotive modules.
