Product details
Overview
TLV2470AIDR from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality in a SOT23-6 package. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±10mA output drive at 180mV from rails, and 250μV typical input offset voltage - enabling precision low-power sensor signal conditioning in battery-operated medical and portable instrumentation.
For engineers reviewing the TLV2470AIDR datasheet, TLV2470AIDR pinout, TLV2470AIDR application, or TLV2470AIDR equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLV2470AIDR uses a CMOS input stage delivering 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), paired with a high-drive output stage capable of ±10mA at 180mV from supply rails. Its 2.8MHz gain-bandwidth product and 1.5V/μs slew rate support stable unity-gain buffer and active filter configurations across 2.7V–6V supplies.
Shutdown mode reduces quiescent current to 1000nA/ch at 5V (350nA/ch at 3V) while placing the output in high-impedance state. The device is fully specified over –40°C to +125°C and features 61° phase margin into 1000pF load - confirming robust stability without external compensation in standard gain configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct operation from single Li-ion (3.0–4.2V), 3.3V logic rails, and 5V systems without regulation. |
| Gain-Bandwidth Product | 2.8MHz - enables stable closed-loop gain ≥10 up to ~280kHz; sufficient for anti-aliasing filters and sensor amplification below 200kHz. |
| Input Offset Voltage | 250μV (typ) - contributes ≤0.5mV error in 2V full-scale 12-bit ADC front-end; no trimming required for <12-bit accuracy. |
| Output Drive Capability | ±10mA at 180mV from rail - drives 10kΩ loads to within 180mV of VDD/GND; supports driving SAR ADC reference buffers and LED indicators. |
| Shutdown Current | 1000nA/ch at 5V - draws <1μA total in shutdown, extending battery life by >100× vs active mode in intermittent-sampling systems. |
| Input Bias Current | 2.5pA - allows use with high-impedance pH electrodes (>100MΩ) and photodiode transimpedance stages without significant DC error. |
| Common-Mode Input Range | 0V to VDD - accepts signals directly from resistive sensors tied to ground or VDD, eliminating level-shifting circuitry. |
Pinout & Package
SOT23-6 package: 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, thermal pad optional (not electrically connected in TLV2470AIDR).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail swing; high-impedance during shutdown when SHDN = low. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; connects to feedback network in inverting configurations. |
| 3 (IN+) | Non-inverting input | High-impedance CMOS node; accepts signals from 0V to VDD without clipping. |
| 4 (GND) | Analog ground reference | Primary return path for input bias currents and output load; must be low-impedance. |
| 5 (SHDN) | Active-low shutdown control | Drives output to high-Z when ≤0.8V; disables amplifier with 1000nA/ch current at 5V. |
| 6 (VDD) | Positive supply | Accepts 2.7V–6V; decoupling capacitor (100nF) required within 5mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3V systems - e.g., 0–3.3V sensor outputs digitized by 3.3V ADCs without level shifters. |
| 600μA/channel supply current | Permits continuous operation in coin-cell-powered devices (e.g., CR2032 lifetime >2 years at 1kHz sampling with sleep). |
| 1000nA/ch shutdown current at 5V | Reduces system standby power to sub-μW levels - critical for IoT edge nodes requiring multi-year battery life. |
| 2.8MHz GBW with 61° phase margin | Supports stable unity-gain follower and 2nd-order active filters without external compensation components. |
| 2.5pA input bias current | Minimizes voltage error across 10MΩ source impedances (<25μV), enabling direct connection to piezoresistive and capacitive sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDR | Higher 6.4MHz GBW but 550μA supply current; no shutdown pin; 150μV max VIO (vs 250μV typ for TLV2470AIDR). | Lacks shutdown - unsuitable for battery-cycled systems; better for always-on signal chains needing higher bandwidth. | Select TLV2461CDR when shutdown is unnecessary and >3MHz closed-loop bandwidth is required. |
| OPA333AIDBVR | Zero-drift architecture; 0.1μV/°C drift, 10μV max VIO; 17μA supply current; no shutdown; SOT23-5 package. | No shutdown function; higher quiescent current makes it unfit for ultra-low-power intermittent operation. | Choose OPA333AIDBVR only when microvolt-level offset stability over temperature is mandatory and power budget allows >17μA continuous draw. |
Compared with TLV2470AIDR, TLV2461CDR trades shutdown capability for higher speed and lower offset, while OPA333AIDBVR eliminates drift at the cost of 28× higher supply current and no power-gating - making TLV2470AIDR the sole choice for shutdown-enabled, sub-1μA standby, rail-to-rail precision amplification.

FAQ
What is the maximum capacitive load the TLV2470AIDR can drive without instability?
The TLV2470AIDR maintains 61° phase margin into 1000pF with 10kΩ load per Figure 18. For loads >10pF, TI recommends adding a 20Ω series resistor (RNULL) between output and capacitance per Figure 42 - enabling stable operation into 100nF ceramic bypass caps or ADC input sampling capacitors without oscillation.
Does the TLV2470AIDR require external compensation for unity-gain stable operation?
No. The TLV2470AIDR is internally compensated for unity-gain stability, verified by 61° phase margin at 1000pF load (Figure 18). No external compensation components are needed for standard non-inverting or inverting configurations with gains ≥1, simplifying layout and reducing BOM count.
What is the actual turn-on time of the TLV2470AIDR from shutdown mode?
The TLV2470AIDR has a 5μs amplifier turn-on time (ton) defined as the interval from SHDN rising to 50% of final supply current, per Electrical Characteristics table on page 6. This enables rapid wake-up for burst-mode sensing without compromising low-power standby.
Can the TLV2470AIDR operate from a 2.5V supply?
No. The absolute minimum supply voltage is 2.7V per Absolute Maximum Ratings (page 3). Operation below 2.7V risks undefined behavior, reduced output swing, and failure to meet AC specifications - designs must ensure VDD ≥2.7V across temperature and tolerance.
How does the input offset voltage of TLV2470AIDR vary with common-mode voltage?
Per Figure 1, TLV2470AIDR's input offset voltage remains stable within ±200μV across the full 0V to VDD common-mode range at 3V supply. This flat VIO vs VICR curve ensures consistent accuracy when amplifying signals near supply rails - critical for single-supply sensor interfaces.
