Product details
Overview
TLV2370IDBVRG4 from Texas Instruments is a single-channel, rail-to-rail input and output operational amplifier with shutdown control, designed for low-power, wide-supply applications. It delivers 3-MHz 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 medical sensors and industrial remote sensing nodes.
For engineers reviewing the TLV2370IDBVRG4 datasheet, TLV2370IDBVRG4 pinout, TLV2370IDBVRG4 application, or TLV2370IDBVRG4 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, and active-low shutdown mode drawing only 25 µA/channel in sleep state.
Technical Context
The TLV2370IDBVRG4 employs CMOS input stage architecture to achieve 1-pA input bias current and rail-to-rail common-mode input range (0 V to VDD), supporting direct interfacing with Li-ion battery rails and microcontroller ADC references. Its unity-gain stable design features 65° phase margin into 100-pF capacitive load and delivers 2.4–3 MHz gain-bandwidth product depending on supply voltage.
Shutdown functionality is implemented via an active-low SHDN pin that disables the amplifier core while maintaining input/output isolation; turnon/turnoff times are specified at 0.8 µs and 1.0 µs respectively with 2-kΩ load, enabling fast power cycling in portable instrumentation.
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 (3.0 V), and ±8-V split supplies. |
| Bandwidth (UGBW) | 3 MHz at VDD ≥ 5 V - enables accurate amplification of audio-band and sensor signals up to ~1.5 MHz closed-loop. |
| Slew Rate | 2.4 V/µs at VDD = 5 V - ensures <1% distortion for 1-VPP signals up to ~380 kHz in unity-gain buffer configuration. |
| Input Bias Current | 1 pA typical - preserves signal integrity in pH electrodes, photodiode transimpedance stages, and high-R sensor bridges. |
| Shutdown Current | 25 µA/channel at VDD = 2.7–5 V - reduces system standby power by >95% versus active mode (550 µA). |
| Input Noise Voltage | 39 nV/√Hz at 1 kHz - suitable for low-level analog front-ends where thermal noise dominates over 1/f noise. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, automotive cabin modules, and white goods motor control feedback paths. |
Pinout & Package
TLV2370IDBVRG4 is packaged in a 6-pin SOT-23 (DBV) with 2.90 mm × 1.60 mm body size, optimized for space-constrained PCB layouts in handheld test equipment and portable medical devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified signal source; rail-to-rail swing (0.1 V to VDD − 0.1 V at 1 mA load) enables full dynamic range utilization. |
| 2 - GND | Ground Reference | Primary return path for input bias current and output load; must be low-impedance connection to minimize noise coupling. |
| 3 - IN+ | Noninverting Input | High-impedance node (1000 GΩ differential resistance); accepts common-mode voltages from 0 V to VDD. |
| 4 - IN− | Inverting Input | Differential input node; matched to IN+ for offset minimization; sensitive to PCB trace parasitics above 1 MHz. |
| 5 - SHDN | Shutdown Control | Active-low logic input; floats to enable (VDD > 2 V), pulled to GND to disable; no external pullup required. |
| 6 - VDD | Positive Supply | Single positive rail input; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability at full bandwidth. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables direct interface with 0–VDD reference systems (e.g., MSP430 ADC inputs) without level-shifting circuitry. |
| 550 µA/channel supply current | Permits continuous operation for >1 year on a single CR2032 coin cell in low-duty-cycle sensor nodes. |
| 1-pA input bias current | Reduces voltage error to <1 µV in 1-MΩ source impedance applications, critical for precision thermistor or strain gauge interfaces. |
| 25 µA/channel shutdown current | Lowers quiescent power to 67.5 nW at 2.7 V, enabling micro-power wake-on-event architectures. |
| 3-MHz bandwidth at 5 V | Supports closed-loop gains up to 10 with >100 kHz small-signal response for active filter and anti-aliasing implementations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371IDBVR | No shutdown pin; 5-pin SOT-23 package; identical electrical specs except IDD(SHDN) = N/A. | Suitable where always-on operation is acceptable and board space is constrained (one fewer pin). | Select TLV2371IDBVR when shutdown functionality is unnecessary and BOM simplification is prioritized. |
| OPA333AIDBVR | Zero-drift architecture; 10-µV max VOS vs 4.5-mV typ for TLV2370IDBVRG4; higher 350-µA supply current; no shutdown. | Better DC accuracy for precision weigh scales or medical diagnostics; less suitable for battery life-critical designs. | Choose OPA333AIDBVR when offset voltage drift over temperature is the dominant error source, not power budget. |

FAQ
What is the maximum recommended supply voltage for TLV2370IDBVRG4?
The maximum recommended supply voltage for TLV2370IDBVRG4 is 16 V, as specified in the Recommended Operating Conditions table. Absolute maximum rating is 16.5 V, but sustained operation above 16 V may impact reliability. This allows use with ±8-V split supplies or high-voltage single-ended rails in industrial control systems.
Does TLV2370IDBVRG4 support rail-to-rail input at 2.7-V supply?
Yes, TLV2370IDBVRG4 supports rail-to-rail input common-mode range (0 V to VDD) at all supply voltages including 2.7 V. This is confirmed in the device description and Electrical Characteristics tables, enabling direct interfacing with low-voltage microcontrollers and battery monitors without external level shifting.
What is the typical input offset voltage of TLV2370IDBVRG4 at 25°C?
The typical input offset voltage of TLV2370IDBVRG4 at 25°C is 4.5 mV, with a maximum of 6 mV over the full −40°C to +125°C temperature range. This value is measured under standard conditions (VIC = VDD/2, VO = VDD/2, RS = 50 Ω) and reflects the inherent matching limitations of its CMOS input stage.
How does the shutdown function behave on TLV2370IDBVRG4?
The TLV2370IDBVRG4 shutdown pin (SHDN) is active-low: pulling it to GND disables the amplifier core and reduces supply current to 25 µA/channel, while leaving it floating or connecting to VDD enables normal operation. No external pullup resistor is required, and the pin exhibits negligible leakage (<100 nA) in either state.
Is TLV2370IDBVRG4 compatible with SOT-23 pick-and-place equipment?
Yes, TLV2370IDBVRG4 uses the industry-standard 6-pin SOT-23 (DBV) package with 0.95-mm pitch and JEDEC MO-178AC footprint. Its 2.90 mm × 1.60 mm body size and coplanar lead geometry are fully compatible with automated assembly processes, including vision-guided placement and reflow soldering per IPC-J-STD-020.
