Product details
Overview
TLV2375IPWR from Texas Instruments is a quad rail-to-rail input/output operational amplifier with integrated shutdown control for channels 1–2 and 3–4, operating from 2.7 V to 16 V supply, delivering 3-MHz bandwidth and 2.4-V/µs slew rate at 550-µA per channel quiescent current, used in battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the TLV2375IPWR datasheet, TLV2375IPWR pinout, TLV2375IPWR application, or TLV2375IPWR equivalent, key selection criteria include its dual-pair shutdown architecture, rail-to-rail output swing down to 2.7 V, −40°C to +125°C industrial temperature rating, and TSSOP-16 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2375IPWR implements CMOS input stage architecture enabling 1-pA input bias current and rail-to-rail common-mode input range (0 V to VDD), supporting high-impedance sensor interfaces. Its unity-gain stable design achieves 3-MHz gain-bandwidth product with 65° phase margin into 100-pF capacitive load.
Shutdown functionality is implemented via two independent active-low control inputs (pins 8 and 9): 1/2SHDN disables channels 1 and 2, while 3/4SHDN disables channels 3 and 4. Each pair draws only 25 µA per channel in shutdown mode at 2.7–5 V supply, enabling selective power gating in multi-channel systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single Li-ion (3.0–4.2 V), dual alkaline (3.0 V), or ±8-V split supplies without level-shifting. |
| Bandwidth (GBW) | 3 MHz - enables accurate amplification of signals up to ~300 kHz in closed-loop gain ≥10 configurations. |
| Slew Rate | 2.4 V/µs - ensures <1% distortion for 1-Vpp signals at 100 kHz in unity-gain buffer applications. | Input Bias Current | 1 pA - minimizes voltage error in high-Z transducer interfaces (e.g., pH electrodes, piezoelectric sensors). |
| Shutdown Current | 25 µA/channel - reduces total system standby power by >95% when unused amplifier pairs are disabled. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, automotive cabin electronics, and white goods motor control feedback paths. |
| Input Noise Voltage | 39 nV/√Hz - maintains SNR >70 dB for 1-kHz signals with 10-kΩ source impedance. |
Pinout & Package
TSSOP-16 package (4.4 mm × 5.0 mm body, 0.65-mm pitch), thermally enhanced for industrial ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier 1 output - rail-to-rail swing (0.1 V to VDD − 0.1 V at 1-mA load) enables direct ADC driving. |
| 2 | 1IN− | Inverting input, channel 1 - high-impedance node (1000 GΩ) suitable for precision current-to-voltage conversion. |
| 3 | 1IN+ | Noninverting input, channel 1 - accepts common-mode voltages from 0 V to VDD, eliminating external level shifters. |
| 4 | VDD | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability at full bandwidth. |
| 5 | 2IN+ | Noninverting input, channel 2 - electrically isolated from channel 1 inputs; no crosstalk above −80 dB at 10 kHz. |
| 6 | 2IN− | Inverting input, channel 2 - matched input capacitance (8 pF) to channel 1 ensures balanced AC response in differential configurations. |
| 7 | 2OUT | Amplifier 2 output - independently buffered; shares VDD/GND but has separate internal biasing for channel isolation. |
| 8 | 1/2SHDN | Active-low shutdown for channels 1 & 2 - logic low (<0.8 V) disables both outputs; floating = enabled. |
| 9 | 3/4SHDN | Active-low shutdown for channels 3 & 4 - allows independent power management of two amplifier pairs. |
| 10 | 3OUT | Amplifier 3 output - identical DC/AC specs to channel 1; usable as reference buffer or active filter stage. |
| 11 | 3IN− | Inverting input, channel 3 - pin-compatible with channel 1; supports cascaded gain stages without layout redesign. |
| 12 | 3IN+ | Noninverting input, channel 3 - same rail-to-rail input range; enables high-side sensing in 3.3-V microcontroller systems. |
| 13 | GND | Ground reference - low-inductance connection required; shared return path for all four channels. |
| 14 | 4IN− | Inverting input, channel 4 - matched offset voltage drift (2 µV/°C) ensures thermal tracking in multi-sensor systems. |
| 15 | 4IN+ | Noninverting input, channel 4 - supports true differential input configuration when paired with channel 3. |
| 16 | 4OUT | Amplifier 4 output - fully specified for 5-mA drive capability into resistive loads, enabling direct LED biasing. |

FAQ
What is the maximum supply voltage for TLV2375IPWR?
The absolute maximum supply voltage for TLV2375IPWR is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage. At 16 V, the device delivers full rail-to-rail output swing and maintains 3-MHz bandwidth, making it suitable for ±8-V split-supply applications or high-voltage single-supply systems like industrial PLC analog outputs.
Does TLV2375IPWR support true rail-to-rail input operation?
Yes, TLV2375IPWR supports true rail-to-rail input operation: its common-mode input voltage range extends from 0 V to VDD across the full temperature range (−40°C to +125°C). This eliminates the need for external level-shifting circuitry when interfacing with 0-V referenced sensors or microcontroller GPIOs, unlike LMV324IPWR which restricts input to VDD − 1.35 V.
How does the dual-pair shutdown function work on TLV2375IPWR?
TLV2375IPWR features two independent active-low shutdown pins: pin 8 (1/2SHDN) controls channels 1 and 2, while pin 9 (3/4SHDN) controls channels 3 and 4. Driving either pin below 0.8 V disables the corresponding pair, reducing supply current to 25 µA per channel. Both pins can be left floating to maintain normal operation - no external pull-up is required.
What is the typical input offset voltage of TLV2375IPWR over temperature?
The typical input offset voltage of TLV2375IPWR is 4.5 mV at 25°C, with a maximum of 6 mV across the full −40°C to +125°C industrial temperature range. Its offset voltage drift is specified at 2 µV/°C, ensuring predictable calibration behavior in thermally varying environments such as automotive cabin sensors or outdoor weather stations.
Is TLV2375IPWR unity-gain stable?
Yes, TLV2375IPWR is unity-gain stable with a phase margin of 65° into a 100-pF capacitive load. It maintains stability without external compensation in standard configurations, including voltage followers and active filters. The datasheet confirms stable operation with 2-kΩ load and 10–100-pF capacitive loads, making it suitable for direct ADC driving and low-noise sensor buffering without added components.
