Product details
Overview
TLV2371IDG4 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 unity-gain bandwidth, 2.4 V/µs slew rate, and 550 µA per-channel supply current across 2.7 V to 16 V operation - enabling precision signal conditioning in battery-powered industrial sensors and portable medical devices.
For engineers reviewing the TLV2371IDG4 datasheet, TLV2371IDG4 pinout, TLV2371IDG4 application, or TLV2371IDG4 equivalent, key selection criteria include its rail-to-rail I/O capability at 2.7-V minimum supply, 1-pA input bias current for high-impedance sensor interfacing, shutdown mode with 25 µA/channel quiescent current, and −40°C to +125°C industrial temperature rating.
Technical Context
The TLV2371IDG4 employs CMOS input stage architecture enabling ultra-low input bias current (1 pA) and rail-to-rail common-mode input range (0 V to VDD). Its fully differential output stage supports rail-to-rail swing under load, maintaining >2.5 V output high and <0.15 V output low at 1 mA with 2.7-V supply.
Shutdown functionality is implemented via active-low SHDN pin (pin 5 in SOIC-8), reducing supply current to 25 µA/channel while preserving fast turnon/turnoff times (0.8 µs / 1 µs). The device operates without phase reversal and maintains stable unity-gain performance up to 100 pF capacitive load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports Li-ion, dual AA/AAA, and ±1.35 V to ±8 V split supplies |
| Unity-Gain Bandwidth | 3 MHz - enables stable closed-loop operation up to ~200 kHz with 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 source interfaces (e.g., pH electrodes, photodiodes) |
| Input Noise Voltage | 39 nV/√Hz at 1 kHz - suitable for low-level analog front-ends requiring <1 µV RMS noise over 10 kHz BW |
| Shutdown Current | 25 µA/channel - reduces system standby power by >95% vs active mode (550 µA) |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, automotive cabin modules, and white goods control |
Pinout & Package
TLV2371IDG4 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/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - rail-to-rail capable, drives ≥10 kΩ loads with <1 mV error |
| 2 | IN− | Inverting input - high-impedance CMOS node; accepts common-mode voltages from GND to VDD |
| 3 | IN+ | Noninverting input - matched to IN−; used for unity-gain buffer or precision instrumentation |
| 4 | GND | Analog ground reference - must be low-impedance connection to minimize PSRR degradation |
| 5 | NC | No internal connection - electrically isolated; may be left unconnected or tied to GND for mechanical stability |
| 6 | OUT | Not applicable - TLV2371 is single-channel; this pin is NC per datasheet Pin Functions table |
| 7 | VDD | Positive supply - accepts 2.7–16 V; decoupling capacitor (0.1 µF) required within 5 mm |
| 8 | NC | No internal connection - confirmed NC in SOIC-8 configuration for TLV2371 (not SHDN) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems - no level-shifting needed for 0–VDD signal chains |
| 1-pA input bias current | Reduces offset drift in high-impedance transducer interfaces (e.g., thermopiles, piezoresistive sensors) |
| 2.7-V minimum supply | Direct compatibility with MSP430 microcontrollers and Li-ion battery discharge curves (2.7–4.2 V) |
| 3-MHz bandwidth at 550 µA | Delivers 5× higher speed-per-power than TLC227x family - critical for handheld test equipment response time |
| −40°C to +125°C operation | Validated performance across full industrial temperature range - no derating required for embedded motor control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371CDR | Same electrical specs but CD-grade (0°C to +70°C) and 5-pin SOT-23 package - lacks SOIC-8 thermal performance and industrial temp range | Not suitable for extended temperature environments; limited PCB heat dissipation capability | Select TLV2371IDG4 when industrial temperature range and SOIC thermal metrics (RθJA = 138.4°C/W) are required |
| TLC2271CD | Higher 1100 µA supply current, 2.2-MHz GBW, no shutdown, O-only rail-to-rail output (not input) | Cannot interface directly with 0-V signals; consumes >2× power in always-on configurations | Choose TLV2371IDG4 for battery life-critical designs needing rail-to-rail input, shutdown, and lower IQ |

FAQ
What is the maximum supply voltage for TLV2371IDG4?
The absolute maximum supply voltage for TLV2371IDG4 is 16.5 V, with recommended operation up to 16 V. Exceeding this risks permanent damage. At 16 V, the device maintains 3-MHz bandwidth and rail-to-rail output swing, supporting legacy 15-V systems and dual ±8-V supplies.
Does TLV2371IDG4 have a shutdown function?
No, TLV2371IDG4 does not include a shutdown pin. Unlike TLV2370 (which has SHDN on pin 5 in SOIC-8), TLV2371IDG4 is the non-shutdown variant - confirmed by TI's Pin Functions table showing pins 5 and 8 as NC in SOIC-8 configuration. Shutdown capability requires TLV2370IDG4 or TLV2373 variants.
What is the input offset voltage specification for TLV2371IDG4?
TLV2371IDG4 has a maximum input offset voltage of 4.5 mV at 25°C and 6 mV over the full −40°C to +125°C industrial temperature range. This is measured with VDD = 2.7–15 V, VIC = VDD/2, VO = VDD/2, and RS = 50 Ω, ensuring predictable DC accuracy in precision sensor signal paths.
Which package type is used by TLV2371IDG4?
TLV2371IDG4 uses the SOIC-8 (D) package with body dimensions of 4.90 mm × 3.91 mm. The "DG4" suffix explicitly denotes this 8-pin small-outline integrated circuit variant, distinct from SOT-23 (DBV) or PDIP (P) options listed for other TLV237x family members.
Can TLV2371IDG4 drive capacitive loads?
Yes, TLV2371IDG4 is unity-gain stable with capacitive loads up to 100 pF, as verified by phase margin ≥65° and gain margin ≥18 dB under RL = 2 kΩ, CL = 100 pF conditions. For loads >100 pF, external isolation resistor (e.g., 10–50 Ω in series with output) is recommended to maintain stability.
