Product details
Overview
TLV2470IDR from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, 2.8MHz gain-bandwidth product, 600μA supply current per channel, and ±10mA output drive at 180mV from rails. It operates from 2.7V to 6V and is designed for low-power sensor signal conditioning in portable medical devices and battery-powered data acquisition systems.
For engineers reviewing the TLV2470IDR datasheet, TLV2470IDR pinout, TLV2470IDR application, or TLV2470IDR equivalent, key selection criteria include rail-to-rail I/O swing, ultra-low shutdown current (350nA/ch at 3V), input bias current of 2.5pA, 250μV typical input offset voltage, and SOT23-6 packaging for high-density layouts.
Technical Context
The TLV2470IDR employs a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD). Its output stage delivers ±10mA into loads while swinging within 180mV of each supply rail, supporting true single-supply operation in low-voltage analog front-ends.
Integrated shutdown logic places the output in high-impedance state and reduces supply current to 350nA/channel at 3V when SHDN ≤ 0.8V, making it suitable for intermittent-sampling architectures where power gating is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct interface with Li-ion, 3.3V, and 5V systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~280kHz. |
| Input Bias Current | 2.5pA - minimizes error in high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance). |
| Input Offset Voltage | 250μV (typ) - ensures <1mV total offset in precision DC-coupled gain stages with moderate gain. |
| Shutdown Supply Current | 350nA/ch at 3V - allows >1-year battery life in wake-on-event sensor nodes with infrequent measurement cycles. |
| Output Drive Capability | ±10mA at 180mV from rail - drives 10kΩ loads fully rail-to-rail and 600Ω loads with ≤500mV headroom. |
| Common-Mode Input Range | 0V to VDD - accepts signals directly from resistive sensors or DACs referenced to ground or VDD. |
Pinout & Package
SOT23-6 package: 2.9mm × 1.6mm footprint, 0.95mm height, thermal pad optional, rated for –40°C to +125°C industrial operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pin; must be left floating or tied to GND for mechanical stability only. |
| 2 (IN−) | Inverting input | Differential node for feedback networks; high-impedance CMOS input (10¹²Ω). |
| 3 (IN+) | Non-inverting input | Accepts rail-to-rail common-mode signals; matched to IN− for low VIO drift. |
| 4 (GND) | Analog ground reference | Primary return path for input bias currents and output load current; requires low-impedance PCB trace. |
| 5 (SHDN) | Active-low shutdown control | Logic-low (≤0.8V) disables amplifier; high-impedance output and 350nA IDD(SHDN) at 3V. |
| 6 (OUT) | Amplifier output | Capable of sourcing/sinking ±10mA while maintaining rail-to-rail swing within 180mV. |
| 7 (VDD) | Positive supply | Single supply input; decoupling capacitor (0.1μF) required within 2mm of pin for stability. |
| 8 (NC) | No internal connection | Unused pin; no electrical function; may be omitted in layout. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3V systems - e.g., 0–3V sensor output amplified to 0–3V ADC input without clipping. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDBVR | Higher 6.4MHz GBW and ±90mA output drive, but 550μA IDD and no shutdown pin. | Better for high-speed, high-current buffering; unsuitable where power gating is required. | Select TLV2461IDBVR only if bandwidth >2.8MHz and shutdown are not needed. |
| OPA316IDBVR | Lower 10μV VIO and 1.3MHz GBW, 100μA IDD, no shutdown, SOT23-5 package. | Superior DC precision for low-frequency sensor amps; lacks shutdown and rail-to-rail output swing. | Choose OPA316IDBVR for ultra-low-offset DC applications without power cycling requirements. |
Compared with TLV2470IDR, TLV2461IDBVR trades shutdown capability and rail-to-rail output for higher speed and drive strength, while OPA316IDBVR sacrifices bandwidth and shutdown for lower offset and quiescent current - making TLV2470IDR the optimal balance for battery-powered, rail-to-rail, shutdown-enabled signal chains.

FAQ
What is the operating temperature range for TLV2470IDR?
The TLV2470IDR is specified for operation from –40°C to +125°C, meeting industrial temperature requirements. This range is confirmed in the "RECOMMENDED OPERATING CONDITIONS" table of the TI datasheet SLOS232E, where the "I-suffix" designation (as in TLV2470IDR) explicitly defines this extended range. The device maintains its 2.8MHz gain-bandwidth product and 250μV input offset voltage specifications across this full range.
Does TLV2470IDR support true rail-to-rail output swing under load?
Yes, TLV2470IDR delivers rail-to-rail output swing with ≤180mV headroom at ±10mA load, as verified in the "ELECTRICAL CHARACTERISTICS" tables (VOH/VOL parameters at IO = ±10mA). At lighter loads (e.g., 2.5mA), swing improves to ≤150mV from rails. This behavior is enabled by its CMOS output stage and is functional across the full 2.7V–6V supply range and –40°C to +125°C temperature range.
How does the shutdown feature of TLV2470IDR behave electrically?
When the SHDN pin is driven ≤0.8V (VIL), TLV2470IDR disables its internal circuitry, placing the output in high-impedance state and reducing supply current to 350nA/channel at 3V (1000nA/ch at 5V). Turn-off time is 250ns, and turn-on time is 5μs, as measured from SHDN logic transition to 50% IDD final value. Output remains high-Z during transition; no glitch or pop occurs.
Can TLV2470IDR drive capacitive loads, and what is the recommended approach?
TLV2470IDR can drive capacitive loads up to 10pF stably without external compensation. For loads >10pF, TI recommends adding a series null resistor (RNULL) of ≥20Ω between the OUT pin and the capacitive load, as shown in Figure 42 of the datasheet. This preserves phase margin above 61° and prevents ringing or oscillation - validated for CL up to 1000pF with RNULL = 50Ω at 3V/5V.
What is the input offset voltage drift over temperature for TLV2470IDR?
The TLV2470IDR has a temperature coefficient of input offset voltage (αVIO) of 0.4μV/°C, as specified in the "ELECTRICAL CHARACTERISTICS" table. Over the full –40°C to +125°C range (165°C span), this results in a maximum drift contribution of 66μV - added to the initial 250μV typical VIO. This low drift supports stable DC accuracy in uncalibrated industrial sensor interfaces without periodic auto-zeroing.
