Product details
Overview
TLV2470IP from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, 2.8MHz gain-bandwidth product, 600μA/channel supply current, and ±10mA output drive at 180mV from rails. It operates from 2.7V to 6V and is specified over –40°C to +125°C for industrial sensor interface and portable medical equipment.
For engineers reviewing the TLV2470IP datasheet, TLV2470IP pinout, TLV2470IP application, or TLV2470IP equivalent, key selection criteria include shutdown current (1000nA/ch at 5V), rail-to-rail I/O swing, input bias current (2.5pA), and SOT23-6 packaging for high-density power-sensitive designs.
Technical Context
The TLV2470IP uses a CMOS input stage enabling ultra-low input bias current (2.5pA) and rail-to-rail common-mode input range (0V to VDD). Its output stage delivers ±10mA into 180mV of either rail and ±35mA into 500mV, supporting high-drive requirements in low-voltage signal conditioning.
Shutdown control is TTL/CMOS-compatible (VIH = 2V, VIL = 0.8V relative to GND), placing outputs in high-impedance state while reducing supply current to 1000nA/channel at 5V. The device maintains stability with capacitive loads ≥10pF when using a series nulling resistor (RNULL ≥20Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - supports stable unity-gain buffer or gain-of-10 amplification up to 280kHz. |
| Supply current per channel | 600μA - enables multi-day battery life in 3V portable systems with continuous operation. |
| Shutdown supply current | 1000nA at 5V - reduces system standby power by >600× versus active mode. |
| Rail-to-rail output swing | ±10mA at 180mV from rail - drives precision ADC reference buffers or low-dropout voltage followers without headroom loss. |
| Input offset voltage | 250μV (typ) - ensures <0.01% error in 2.5V full-scale instrumentation amplifier front-ends. |
| Input bias current | 2.5pA - minimizes voltage error across high-impedance sensor sources (e.g., pH electrodes, photodiodes). |
| Supply voltage range | 2.7V to 6V - interoperates with Li-ion (3.0–4.2V), 3.3V logic, and dual-supply ±3V systems. |
Pinout & Package
SOT23-6 package: 1.6mm × 2.9mm footprint, 0.95mm height, thermal pad optional, RoHS-compliant, rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; requires RNULL ≥20Ω for CL >10pF stability. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; connects to feedback network in standard op-amp configurations. |
| 3 (IN+) | Non-inverting input | Accepts signals from 0V to VDD; used for sensor biasing or reference buffering. |
| 4 (GND) | Analog ground | Reference for all input/output voltages; must be low-impedance path to system ground plane. |
| 5 (SHDN) | Shutdown enable | Active-high logic input; drives to VDD to enable, to GND to enter 1000nA shutdown mode. |
| 6 (VDD) | Positive supply | Accepts 2.7–6V; decoupling capacitor (0.1μF) required within 5mm of pin for PSRR optimization. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3V systems-no external level-shifting needed for 0–3V sensor signals. |
| Ultra-low shutdown current | 1000nA/channel at 5V allows multi-year battery life in intermittent-sampling data loggers. |
| High output drive capability | ±35mA at 500mV from rail supports direct driving of 10kΩ ADC inputs or LED indicators without buffer stages. |
| Low input bias current | 2.5pA preserves signal integrity from megaohm-level sources like thermistors or piezoelectric sensors. |
| Specified over extended temperature | –40°C to +125°C rating qualifies TLV2470IP for under-hood automotive or industrial motor-control feedback loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2470CDR | Same electrical specs; C-suffix (0°C to +70°C) vs I-suffix; SOT23-6 tape-and-reel packaging. | Commercial temperature grade only; unsuitable for under-hood or industrial environments. | Select TLV2470CDR only for cost-sensitive consumer electronics with ambient ≤70°C. |
| OPA333AIDBVR | Zero-drift architecture; 0.1μV/°C offset drift vs TLV2470IP's 0.4μV/°C; 350nA shutdown current at 5V. | Higher precision DC performance but lower 350kHz GBW limits AC bandwidth-critical applications. | Choose OPA333AIDBVR when long-term DC stability dominates over speed; avoid where >1MHz small-signal response is required. |
Compared with TLV2470IP, TLV2470CDR trades industrial temperature range for lower cost and tape-and-reel convenience, while OPA333AIDBVR sacrifices bandwidth for sub-microvolt offset stability-making TLV2470IP optimal for balanced speed, power, and ruggedness in sensor front-ends.

FAQ
What is the maximum capacitive load the TLV2470IP can drive without oscillation?
The TLV2470IP remains stable with capacitive loads up to 10pF when directly connected. For loads exceeding 10pF, a series nulling resistor (RNULL ≥20Ω) must be placed between the OUT pin and the load capacitance to maintain phase margin above 61°, as verified in the datasheet Figure 18 and Application Information section.
Does the TLV2470IP support true rail-to-rail input common-mode range?
Yes, the TLV2470IP supports a common-mode input voltage range from 0V to VDD across its full operating supply range (2.7V to 6V), confirmed in the Recommended Operating Conditions table and validated in Figure 1 and Figure 2 of the TLV2470IP datasheet.
What is the typical turn-on time for the TLV2470IP after asserting the SHDN pin high?
The TLV2470IP exhibits a typical amplifier turn-on time of 5μs, defined as the interval between SHDN rising to VDD and supply current reaching 50% of its final active value, as measured under VDD = 3V and documented in the Operating Characteristics table on page 5 of the datasheet.
Can the TLV2470IP operate from a single 2.7V supply while delivering ±10mA output current?
Yes, the TLV2470IP is fully specified at 2.7V supply and delivers ±10mA output current while swinging within 180mV of each rail, as confirmed in the "High Output Drive Capability" feature list and Electrical Characteristics tables for both 3V and 5V conditions.
How does the input offset voltage of the TLV2470IP vary with temperature?
The TLV2470IP has a temperature coefficient of input offset voltage (αVIO) of 0.4μV/°C, meaning its offset drifts less than 50μV over a –40°C to +125°C range-verified in the Electrical Characteristics table and supported by Figure 1 and Figure 2 showing VIO vs VICR across temperature.
