Product details
Overview
TLV2470IDBVR from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, designed for ultra-low-power signal conditioning in battery-operated systems. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±10mA output drive at 180mV from rails, and 250μV typical input offset voltage across –40°C to +125°C. It serves as a precision, low-quiescent-current front-end amplifier in portable medical sensors and industrial data acquisition.
For engineers reviewing the TLV2470IDBVR datasheet, TLV2470IDBVR pinout, TLV2470IDBVR application, or TLV2470IDBVR equivalent, this page provides verified technical context, package-specific pin definitions, real-world use cases, and validated alternative options - all grounded in TI's SLOS232E datasheet and official ordering information for the I-suffix industrial-grade SOT23-6 variant.
Technical Context
The TLV2470IDBVR implements a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing (within 180mV of each rail under 10mA load). Its internal architecture supports stable operation with capacitive loads ≥10pF only when series nulling resistance (RNULL ≥20Ω) is used at the output.
Shutdown control is active-low: applying SHDN ≤0.8V places the amplifier in ultra-low-power mode (350nA/channel at 3V, 1000nA/channel at 5V), disabling output stage and placing output in high-impedance state. The device is fully specified over VDD = 2.7V–6V and operates across –40°C to +125°C without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct connection to single-cell Li-ion (3.0–4.2V), 3.3V logic, and 5V legacy rails without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - enables stable closed-loop gain up to ~28 at 100kHz for sensor amplification with adequate phase margin. |
| Input Bias Current | 2.5pA (typ) - ensures minimal error in high-impedance source interfaces (e.g., pH electrodes, piezoresistive bridges). |
| Output Drive Capability | ±10mA at 180mV from rail - drives 10kΩ loads to full scale while maintaining rail-to-rail dynamic range in 3V systems. |
| Shutdown Supply Current | 350nA/channel at 3V - extends battery life in intermittent-sampling applications (e.g., wearable ECG monitors). |
| Input Offset Voltage | 250μV (typ) - limits DC error to <0.5% of full-scale in 50mV sensor outputs without trimming. |
| Common-Mode Input Range | 0V to VDD - accepts signals directly referenced to ground or VDD in single-supply configurations. |
Pinout & Package
SOT23-6 package (DBV): 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, moisture sensitivity level 1, rated for industrial temperature range (–40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage swing; requires RNULL ≥20Ω for stability with >10pF capacitive loads. |
| 2 - IN− | Inverting input | High-impedance CMOS node; bias current 2.5pA enables use with MΩ-level feedback networks. |
| 3 - IN+ | Non-inverting input | Accepts common-mode signals from 0V to VDD; matched to IN− for low offset drift. |
| 4 - GND | Analog ground reference | Must be connected to clean system ground plane; separates analog return from digital or power return paths. |
| 5 - SHDN | Active-low shutdown control | Pulled low (≤0.8V) to disable amplifier; high-impedance when floating; must be driven by logic-level signal. |
| 6 - VDD | Positive supply | Accepts 2.7V–6V; decoupling capacitor (0.1μF ceramic) required within 5mm of pin for PSRR integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Higher GBW (10MHz), lower noise (11nV/√Hz), but no shutdown; 500μA supply current. | Lacks shutdown function - unsuitable for duty-cycled systems requiring ultra-low standby current. | Choose when bandwidth and noise dominate over power gating; verify layout accommodates higher-speed stability requirements. |
| TLV9001IDBVR | Lower supply current (60μA), rail-to-rail I/O, but reduced GBW (1MHz); shutdown available (IDD(SHDN) = 150nA). | Better standby efficiency but insufficient bandwidth for >10kHz signal chains; optimized for sub-1kHz sensor apps. | Prefer for always-on, ultra-low-power monitoring (e.g., CO₂ sensors); avoid where 2.8MHz settling or THD+N <0.1% at 1kHz is required. |
Compared with TLV2470IDBVR, OPA316IDBVR trades shutdown capability for higher speed and lower noise, while TLV9001IDBVR prioritizes minimum active and shutdown current at the expense of bandwidth - making TLV2470IDBVR the balanced choice for 2.8MHz-capable, shutdown-enabled, industrial-temperature signal conditioning.

FAQ
What is the maximum capacitive load the TLV2470IDBVR can drive without oscillation?
The TLV2470IDBVR becomes unstable with capacitive loads exceeding 10pF when connected directly to the output. To maintain phase margin >60°, TI specifies adding a series nulling resistor (RNULL) ≥20Ω between the OUT pin and the load capacitance. This configuration allows stable operation with loads up to 1000pF, as confirmed in Figure 18 and Application Information section of the SLOS232E datasheet for TLV2470IDBVR.
Does the TLV2470IDBVR support true rail-to-rail output swing under 10mA load?
Yes - the TLV2470IDBVR delivers rail-to-rail output swing within 180mV of each supply rail when sourcing or sinking ±10mA, as specified in the "High Output Drive Capability" section of the datasheet. At lighter loads (e.g., ±2.5mA), it achieves even tighter swing (≤70mV from rails at 3V). This behavior is validated across the full –40°C to +125°C temperature range for TLV2470IDBVR.
What logic levels activate and deactivate shutdown on the TLV2470IDBVR?
Shutdown on TLV2470IDBVR is activated when SHDN voltage ≤0.8V (VIL) and deactivated when SHDN voltage ≥2.0V (VIH), both referenced to GND. These thresholds are guaranteed over temperature and supply voltage (2.7V–6V). Driving SHDN with standard 3.3V or 5V GPIO pins ensures reliable control; floating SHDN defaults to active mode due to internal pull-down.
How does the input offset voltage of TLV2470IDBVR vary with temperature?
The TLV2470IDBVR has a temperature coefficient of input offset voltage (αVIO) of 0.4μV/°C, meaning offset drift is bounded to ±50μV over the full –40°C to +125°C range. At 25°C, typical VIO is 250μV; worst-case full-range value is 1800μV for the I-suffix grade, as documented in the Electrical Characteristics tables of the SLOS232E datasheet for TLV2470IDBVR.
Can TLV2470IDBVR operate from a 2.7V supply while maintaining 2.8MHz gain-bandwidth?
Yes - the TLV2470IDBVR maintains its 2.8MHz gain-bandwidth product down to VDD = 2.7V, as shown in Figure 22 ("Gain-Bandwidth Product vs Supply Voltage") of the SLOS232E datasheet. Performance remains consistent across the entire 2.7V–6V range, with no degradation in bandwidth, slew rate, or output drive capability at minimum supply.
