Product details
Overview
TLV2370IDBVT 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/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 TLV2370IDBVT datasheet, TLV2370IDBVT pinout, TLV2370IDBVT application, or TLV2370IDBVT 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 standby - critical for portable and safety-monitored systems.
Technical Context
The TLV2370IDBVT uses 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 interface with resistive bridges and pH electrodes without level-shifting. Its unity-gain-stable design provides 3-MHz gain-bandwidth product and 65° phase margin into 100-pF capacitive loads, ensuring robust stability in active filter and transimpedance configurations.
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 under 2-kΩ load, enabling fast power cycling in duty-cycled measurement 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 external regulators. |
| 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 on 1-VPP signals at 100 kHz in unity-gain follower mode. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z sensor interfaces (e.g., thermistors, photodiodes, pH probes). |
| Shutdown Current | 25 µA/channel - reduces system standby power by >95% vs active mode (550 µA), extending battery life in intermittent-sampling devices. |
| Input Noise Voltage | 39 nV/√Hz at 1 kHz - suitable for low-level analog front-ends where signal amplitudes are sub-millivolt. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, automotive cabin modules, and white goods motor control feedback paths. |
Pinout & Package
TLV2370IDBVT is housed in a 6-pin SOT-23 package (DBV), measuring 2.90 mm × 1.60 mm, with exposed pad not present and moisture sensitivity level (MSL) rated per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Output | Amplified signal source capable of sourcing/sinking ±5 mA at 2.7 V and ±16 mA at 15 V; rail-to-rail swing within 100 mV of rails at 1-mA load. |
| GND (Pin 2) | Ground Reference | Primary return path for input bias, output current, and shutdown logic; must be low-impedance connection to minimize PSRR degradation. |
| IN+ (Pin 3) | Noninverting Input | High-impedance CMOS node (1000 GΩ differential resistance); accepts common-mode voltages from 0 V to VDD. |
| IN− (Pin 4) | Inverting Input | Matches IN+ in impedance and voltage range; used for feedback networks and differential gain configurations. |
| SHDN (Pin 5) | Shutdown Control | Active-low digital input; pulls to GND to disable amplifier (IDD drops to 25 µA); floats high for normal operation; no pull-up required. |
| VDD (Pin 6) | Positive Supply | Single positive rail input; supports 2.7–16 V; internal regulation ensures stable biasing across full voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems - e.g., 0–2.7 V input maps linearly to 0–2.7 V output without clipping. |
| Ultra-low input bias current (1 pA) | Reduces offset drift in high-impedance transducer circuits (e.g., 10-MΩ thermistor dividers), maintaining accuracy over temperature. |
| 3-MHz bandwidth at 550 µA | Delivers 10× higher speed-per-power than legacy TLC227x family, enabling faster settling in portable test equipment front-ends. |
| Industrial temperature range (−40°C to +125°C) | Validated for continuous operation in harsh environments including motor drive current-sense amplifiers and HVAC control boards. |
| Low-power shutdown mode (25 µA/channel) | Allows microcontroller-driven power gating in multi-channel sensor arrays - e.g., sequential activation of glucose meter electrode channels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371IDBVT | No shutdown pin; 5-pin SOT-23; identical bandwidth, slew rate, and supply current. | Lacks power-gating capability; unsuitable for battery-cycled systems but simpler layout and lower cost where always-on operation is acceptable. | Select TLV2371IDBVT when shutdown is unnecessary and board space is constrained - same footprint minus one pin. |
| OPA333AIDBVR | Zero-drift architecture; 17-µV max VOS vs 4.5-mV typical for TLV2370IDBVT; 17 µA quiescent current; no shutdown. | Better DC precision for weigh scales or strain gauges; lower power but no rail-to-rail output swing below 100 mV of rails. | Choose OPA333AIDBVR for ultra-low-offset, low-drift applications where 3-MHz bandwidth is sufficient and shutdown is not required. |
Compared with TLV2371IDBVT, TLV2370IDBVT adds active shutdown for energy-sensitive designs; compared with OPA333AIDBVR, it trades DC precision for rail-to-rail output swing, wider supply range, and integrated power control - making it optimal for mixed-signal portable instrumentation.

FAQ
What is the maximum supply voltage for TLV2370IDBVT?
The absolute maximum supply voltage for TLV2370IDBVT 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 maintains full rail-to-rail output swing and 3-MHz bandwidth, enabling compatibility with ±8-V split supplies or high-voltage battery stacks in industrial motor control feedback paths.
Does TLV2370IDBVT require external pull-up on the SHDN pin?
No, TLV2370IDBVT does not require an external pull-up resistor on the SHDN pin. The pin is internally biased and functions correctly when left floating (defaulting to active mode) or driven actively low (0 V) to enter shutdown. Driving SHDN to VDD is not recommended; instead, tie to GND or control via open-drain GPIO for reliable power gating in microcontroller-based systems using TLV2370IDBVT.
Can TLV2370IDBVT drive capacitive loads?
Yes, TLV2370IDBVT is unity-gain stable and characterized for capacitive loads up to 100 pF, with 65° phase margin at that level. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to maintain stability. This capability supports direct driving of ADC input capacitors and long PCB traces in data acquisition systems using TLV2370IDBVT as a buffer stage.
What is the input common-mode voltage range of TLV2370IDBVT?
The input common-mode voltage range of TLV2370IDBVT extends from 0 V to VDD - a true rail-to-rail input specification. This allows the device to accurately amplify signals referenced to ground or near the positive rail, such as outputs from resistive sensors or DACs operating at the same supply. No external level-shifting circuitry is needed, simplifying designs in single-supply portable systems using TLV2370IDBVT.
How does TLV2370IDBVT compare to TLC2272 in battery-powered applications?
TLV2370IDBVT draws 550 µA/channel versus 1100 µA/channel for TLC2272, cutting supply current nearly in half - critical for coin-cell or Li-ion powered devices. It also operates down to 2.7 V (vs 4 V for TLC2272), enabling compatibility with depleted batteries and ultra-low-voltage MCUs like the MSP430. Both offer rail-to-rail output, but only TLV2370IDBVT provides rail-to-rail input and shutdown, making it superior for energy-constrained TLV2370IDBVT deployments.
