Product details
Overview
TLV2371IPG4 from Texas Instruments is a single-channel, rail-to-rail input and output operational amplifier optimized for low-power, wide-supply applications. It delivers 3-MHz bandwidth, 2.4 V/µs slew rate, and 550 µA supply current per channel across 2.7 V to 16 V operation, with shutdown capability (25 µA/channel in SHDN mode) and 1 pA input bias current - enabling precision sensing in battery-powered medical and industrial instrumentation.
For engineers reviewing the TLV2371IPG4 datasheet, TLV2371IPG4 pinout, TLV2371IPG4 application, or TLV2371IPG4 equivalent, key selection criteria include its rail-to-rail I/O swing at 2.7-V minimum supply, −40°C to +125°C industrial temperature rating, ultra-low input bias current, and compatibility with Li-ion and MSP430-based systems where power efficiency and input impedance are critical.
Technical Context
The TLV2371IPG4 employs 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 without level-shifting. Its unity-gain-stable design achieves 3 MHz gain-bandwidth product with 2.4 V/µs slew rate under 5 V supply, maintaining phase margin >65° into 100 pF capacitive loads.
Shutdown functionality is implemented via active-low SHDN pin (pin 5 in SOIC-8), reducing quiescent current to 25 µA/channel while preserving fast turnon/turnoff times (0.8 µs / 1 µs). The device operates over full industrial temperature range with specified offset voltage drift of 2 µV/°C and input-referred noise of 39 nV/√Hz at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell Li-ion (3.0–4.2 V), dual alkaline (3 V), and ±8 V split supplies. |
| Bandwidth (GBW) | 3 MHz - enables stable closed-loop operation up to ~200 kHz in unity-gain buffer or 10× gain configurations. |
| Slew Rate | 2.4 V/µs - supports 1-V step response settling within 2 µs at 0.1% for signal conditioning in portable test equipment. |
| Input Bias Current | 1 pA - preserves accuracy in high-Z pH sensors, photodiode transimpedance stages, and electrochemical biosensors. |
| Shutdown Current | 25 µA/channel - reduces system standby power by >95% vs active mode (550 µA), critical for intermittent-sampling devices. |
| Input Noise Voltage | 39 nV/√Hz @ 1 kHz - limits contribution to total system noise floor in low-level analog front-ends (e.g., glucose meter amplifiers). |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, white goods motor control feedback, and automotive cabin ambient sensing. |
Pinout & Package
TLV2371IPG4 is packaged in an 8-pin SOIC (D package) with 4.90 mm × 3.91 mm body size and standard JEDEC MS-012AC footprint. Pin 1 is marked by a molded dot or beveled edge.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - rail-to-rail swing (0.1 V to VDD − 0.1 V at 1 mA load) enables direct interface to ADC reference or microcontroller GPIO. |
| 2 | IN− | Inverting input - high-impedance node (1000 GΩ differential resistance) suitable for precision feedback networks. |
| 3 | IN+ | Noninverting input - common-mode range extends to both rails, allowing direct connection to grounded sensors or resistive dividers. |
| 4 | GND | Analog ground reference - must be connected to clean system ground plane; separates signal return from digital/power grounds. |
| 5 | SHDN | Active-low shutdown control - logic-low ≤0.8 V disables amplifier; floating or logic-high ≥2 V enables operation. |
| 6 | OUT | No connection - NC pin (not internally bonded); must be left unconnected or tied to GND for mechanical stability. |
| 7 | VDD | Positive supply - accepts 2.7–16 V; bypass capacitor (0.1 µF ceramic) required between pin 7 and pin 4 for stability. |
| 8 | NC | No internal connection - unused pin; electrically isolated and may be left floating or grounded per layout best practices. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization with 2.7-V supply - eliminates need for level-shifting in low-voltage microcontroller systems. |
| 550 µA/channel supply current | Supports continuous operation in handheld blood glucose meters with >100-hour battery life on two AAA cells. |
| 1 pA input bias current | Minimizes voltage error in 10-MΩ+ sensor interfaces (e.g., thermistor bridges, piezoelectric transducers) without external guarding. |
| 3-MHz bandwidth at low power | Provides sufficient speed for active filters (e.g., 2nd-order anti-aliasing at 100 kHz) without compromising quiescent current budget. |
| −40°C to +125°C operation | Meets extended temperature requirements for industrial PLC analog I/O modules and motor drive current-sense amplification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371IDBVR | Same electrical specs, but in 5-pin SOT-23 package (2.90 mm × 1.60 mm) - no SHDN pin, fixed active operation. | Used where board space is constrained and shutdown is unnecessary (e.g., always-on sensor nodes). | Select TLV2371IDBVR only if PCB layout cannot accommodate SOIC-8 or shutdown control is omitted from system architecture. |
| TLC2271CD | Higher supply current (1100 µA/channel), no shutdown, wider offset voltage spec (300 µV max), same 2.2-MHz GBW and rail-to-rail output only. | Preferred in legacy designs requiring higher drive strength (±3.6 V/µs slew rate) but tolerating higher power draw. | Choose TLC2271CD when interfacing with heavy capacitive loads (>1000 pF) or where faster slew rate outweighs battery-life impact. |
Compared with TLV2371IDBVR and TLC2271CD, TLV2371IPG4 uniquely combines shutdown capability, 1 pA input bias, and 3-MHz bandwidth in an industry-standard SOIC-8 package - making it optimal for new designs prioritizing precision, low power, and thermal robustness in portable and industrial settings.

FAQ
What is the maximum recommended supply voltage for TLV2371IPG4?
The maximum recommended supply voltage for TLV2371IPG4 is 16 V, as specified in the Recommended Operating Conditions table. Absolute maximum rating is 16.5 V, but sustained operation above 16 V risks reliability degradation. This allows use with ±8-V split supplies or single-ended 12-V/15-V rails in industrial control systems.
Does TLV2371IPG4 support true rail-to-rail input common-mode range?
Yes, TLV2371IPG4 supports rail-to-rail input common-mode range from 0 V to VDD, verified across the full −40°C to +125°C temperature range. This enables direct interfacing with grounded sensors or resistive dividers without external level-shifting circuitry, unlike many competing amplifiers limited to VDD − 1.35 V.
What is the typical output voltage swing for TLV2371IPG4 at 5 V supply and 1 mA load?
At 5 V supply and 1 mA load, TLV2371IPG4 delivers a typical high-level output voltage (VOH) of 4.93 V and low-level output voltage (VOL) of 0.1 V - achieving >98% of rail-to-rail swing. These values are confirmed at 25°C and remain within 4.85 V / 0.15 V across the full industrial temperature range.
Can TLV2371IPG4 be used in single-supply sensor applications below 3 V?
Yes, TLV2371IPG4 is fully specified down to 2.7 V supply, making it compatible with partially discharged Li-ion cells (≥2.7 V) and two-cell alkaline batteries (3.0 V nominal). Its rail-to-rail I/O and 1 pA input bias ensure accuracy even at minimum supply, unlike older op-amps requiring ≥4.5 V.
Is the SHDN pin of TLV2371IPG4 compatible with standard CMOS logic levels?
Yes, the SHDN pin of TLV2371IPG4 is CMOS-compatible: logic-low ≤0.8 V (relative to GND) activates shutdown, and logic-high ≥2 V enables operation. It draws <100 nA leakage current, allowing direct connection to MSP430 GPIO pins without additional level-shifting or pull-up resistors.
