Product details
Overview
TLV2371ID 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 gain-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). It is used in portable blood glucose systems and remote sensing where precision, low quiescent current, and rail-to-rail swing are critical.
For engineers reviewing the TLV2371ID datasheet, TLV2371ID pinout, TLV2371ID application, or TLV2371ID equivalent, key selection considerations include its 1-pA input bias current, −40°C to +125°C industrial temperature range, 5-pin SOIC package, shutdown control interface, and compatibility with Li-ion and microcontroller-supplied rails.
Technical Context
The TLV2371ID employs CMOS input stage architecture enabling ultra-low input bias current (1 pA) and high-impedance sensor interfacing. Its rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 150 mV of rails at 1 mA load) support full dynamic range utilization in single-supply systems.
It integrates an active-low shutdown pin (SHDN) that reduces supply current to 25 µA/channel while preserving fast turnon/turnoff times (0.8 µs / 1 µs). The device maintains stable unity-gain operation with ≥65° phase margin into 100-pF capacitive loads, supporting direct driving of ADC inputs or filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports Li-ion (3.0–4.2 V), dual AA/AAA (3 V), and ±8-V split supplies |
| Gain-Bandwidth Product | 3 MHz - enables stable closed-loop operation up to ~200 kHz at gain = 15 |
| Slew Rate | 2.4 V/µs - supports 1-Vpp signals up to ~380 kHz without distortion |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z sensor interfaces (e.g., pH electrodes, photodiodes) |
| Input Offset Voltage | 4.5 mV (typ) - ensures <0.1% error in 4.5-V full-scale measurement systems |
| Shutdown Current | 25 µA/channel - extends battery life in intermittent-sampling applications like handheld meters |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation and automotive under-hood environments |
Pinout & Package
TLV2371ID is housed in an 8-pin SOIC (D) package with 4.90 mm × 3.91 mm body size and standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - rail-to-rail capable, drives 10-kΩ loads to within 150 mV of rails |
| 2 | IN− | Inverting input - high-impedance CMOS node, sensitive to PCB leakage and ESD |
| 3 | IN+ | Noninverting input - accepts common-mode voltages from 0 V to VDD |
| 4 | GND | Analog ground reference - must be low-impedance and separated from digital ground |
| 5 | NC | No internal connection - electrically isolated; may be left unconnected or tied to GND for mechanical stability |
| 6 | OUT | Not applicable - TLV2371ID is single-channel; this pin is NC per datasheet pin function table |
| 7 | VDD | Positive supply - accepts 2.7–16 V; bypass with 100-nF ceramic capacitor near pin |
| 8 | NC | No internal connection - confirmed in SOIC pin function table; not used |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371DBVR | Same electrical specs; 5-pin SOT-23 package (2.90 mm × 1.60 mm), no NC pins | Better suited for space-constrained PCBs; lacks SOIC's mechanical robustness and thermal mass | Select TLV2371DBVR for ultra-compact designs; choose TLV2371ID for manual assembly, thermal stability, or legacy SOIC footprints |
| TLV2461CDR | Higher 6.4-MHz GBW and 1.6-V/µs slew rate, but 550-µA IQ and no shutdown; 1300-pA input bias | Preferred for higher-speed signal chains where shutdown is unnecessary and sensor impedance <100 MΩ | Choose TLV2461CDR when bandwidth >3 MHz is required and shutdown is not needed; TLV2371ID remains optimal for low-IQ + shutdown + ultra-low IB |
Compared with TLV2371DBVR, TLV2371ID offers superior thermal dissipation (RθJA = 138.4°C/W vs 228.5°C/W) and mechanical handling; versus TLV2461CDR, it trades bandwidth for 1000× lower input bias current and integrated shutdown-critical for high-Z, battery-sensitive systems.

FAQ
What is the maximum supply voltage for TLV2371ID?
The absolute maximum supply voltage for TLV2371ID 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 supports ±8-V split supplies and maintains full rail-to-rail output swing and 3-MHz bandwidth, making it suitable for legacy industrial equipment upgrades.
Does TLV2371ID have a shutdown feature?
No, TLV2371ID does not include a shutdown feature. Only TLV2370, TLV2373, and TLV2375 variants in the TLV237x family integrate active-low SHDN pins. TLV2371ID is the non-shutdown single-channel variant; its pinout omits SHDN and uses two NC pins instead. For shutdown capability, engineers should select TLV2370ID or TLV2370DBVR.
What is the input offset voltage specification for TLV2371ID?
The input offset voltage for TLV2371ID is 4.5 mV (typical) at 25°C, with a maximum of 6 mV over the full −40°C to +125°C temperature range. This value is measured with VDD = 2.7–15 V, common-mode input at VDD/2, and output at VDD/2. The low drift of 2 µV/°C ensures minimal calibration drift in temperature-varying environments.
Which package types are available for TLV2371ID?
TLV2371ID is specifically the 8-pin SOIC (D) package variant. Other TLV2371 options include TLV2371DBVR (5-pin SOT-23) and TLV2371P (8-pin PDIP). The "ID" suffix denotes the SOIC package per TI's orderable addendum; body size is 4.90 mm × 3.91 mm with standard JEDEC MS-012AC footprint and 1.27-mm lead pitch.
Can TLV2371ID drive capacitive loads?
Yes, TLV2371ID is stable driving up to 100 pF capacitive loads with ≥65° phase margin, as verified in the datasheet's typical characteristics (Figure 20). For loads >100 pF, external series resistance (e.g., 10–50 Ω) between the output and capacitance is recommended to maintain stability. This capability supports direct connection to ADC sample capacitors and RC anti-aliasing filters without added op-amp isolation stages.
