Product details
Overview
TLV2470CDRG4 from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality in a SOT-23-6 package. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±10mA output drive at 180mV from rails, and 250μV typical input offset voltage. It is designed for low-voltage sensor signal conditioning in battery-powered medical and portable instrumentation.
For engineers reviewing the TLV2470CDRG4 datasheet, TLV2470CDRG4 pinout, TLV2470CDRG4 application, or TLV2470CDRG4 equivalent, this page provides verified technical context, real-world design meaning of specifications, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLV2470CDRG4 employs a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0 V to VDD). Its output stage supports true rail-to-rail swing-reaching within 180mV of both supply rails under ±10mA load-and delivers ±35mA at 500mV from rails for non-RRO configurations.
It integrates an active-low shutdown terminal (SHDN) that reduces supply current to 350nA/channel at 3V (1000nA at 5V), placing outputs in high-impedance state. Fully specified across 2.7V–6V supply and –40°C to +125°C, it targets precision, low-power analog front-ends where dynamic range and quiescent power are co-constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8 MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~280 kHz without phase margin collapse. |
| Supply current per channel | 600 μA - allows continuous operation for >1 year on a single CR2032 coin cell in always-on sensor monitoring. |
| Input offset voltage (typ) | 250 μV - contributes ≤0.5% error in 50mV full-scale thermocouple or bridge sensor outputs. |
| Rail-to-rail I/O | Inputs accept 0 V to VDD; outputs swing to within 180 mV of rails at ±10 mA - maximizes usable dynamic range in 3.3V systems. |
| Shutdown current (3V) | 350 nA - reduces system standby power to sub-μW level, critical for IoT endpoint wake-on-event architectures. |
| Output drive capability | ±35 mA at 500 mV from rail - directly drives 100Ω transmission lines or LED indicators without external buffers. |
| Input bias current | 2.5 pA - permits use with >100 MΩ source impedances (e.g., pH electrodes, piezoelectric sensors) without significant DC error. |
Pinout & Package
SOT-23-6 package: 2.9 mm × 1.6 mm × 1.1 mm body, gull-wing leads, moisture sensitivity level 1, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage with ±35mA sourcing/sinking capability; requires series resistor ≥20Ω for >10pF capacitive loads. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; connects to feedback network in inverting configurations or reference in transimpedance designs. |
| 3 (IN+) | Non-inverting input | Accepts common-mode signals from 0 V to VDD; used for sensor excitation buffering or single-ended to differential conversion. |
| 4 (GND) | Analog ground reference | Must be star-connected to system AGND; separates noise-sensitive analog return from digital/power grounds. |
| 5 (SHDN) | Active-low shutdown control | Pulled low (<0.8 V) disables amplifier; pulled high (>2 V) enables operation; no external pull-up required in most MCU interfaces. |
| 6 (VDD) | Positive supply | Operates from 2.7 V to 6 V; decoupling capacitor (0.1 μF X7R) required within 3 mm of pin for stability at full bandwidth. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3V supply in precision sensor interfaces-no level-shifting or dual supplies needed. |
| 600μA/channel quiescent current | Supports always-on analog signal chains in portable devices while maintaining >2.8MHz bandwidth for transient capture. |
| 350nA shutdown current at 3V | Reduces total system standby power to <1μW, extending shelf life and enabling multi-year battery operation. |
| 2.5pA input bias current | Permits direct connection to high-impedance sources (e.g., photodiode, electret mic, strain gauge) without guard traces. |
| ±35mA output drive at 500mV from rail | Eliminates need for external driver stages when interfacing with ADC references, DAC buffers, or low-impedance actuators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2460CDR | Higher 6.4MHz GBW but 550μA supply current; no shutdown pin; 150μV max VIO vs 250μV typ for TLV2470CDRG4. | Lacks shutdown function-unsuitable for duty-cycled sensor nodes; better for continuous high-speed filtering. | Select TLV2460CDR only when bandwidth >4MHz is required and shutdown is unnecessary. |
| OPA333AIDBVR | Zero-drift architecture; 0.1μV/°C drift vs 0.4μV/°C for TLV2470CDRG4; 17μA supply current; no shutdown. | Superior long-term DC stability but higher quiescent current-ideal for precision DC-coupled systems, not low-power AC sensing. | Choose OPA333AIDBVR for <0.5μV total drift over temperature; retain TLV2470CDRG4 for sub-μA shutdown and 2.8MHz balance. |
Compared with TLV2470CDRG4, TLV2460CDR trades shutdown capability for higher bandwidth and lower offset, while OPA333AIDBVR sacrifices ultra-low power for near-zero drift-making TLV2470CDRG4 the optimal choice for battery-constrained RRO signal chains requiring periodic wake-up.

FAQ
What is the maximum capacitive load the TLV2470CDRG4 can drive without external compensation?
The TLV2470CDRG4 becomes unstable with capacitive loads exceeding 10pF when directly connected. For reliable operation, a series null resistor (RNULL ≥20Ω) must be placed between the OUT pin and the load capacitance, as confirmed in TI's Application Information section (Figure 42). This preserves phase margin above 60° across all supply voltages and temperatures.
Does the TLV2470CDRG4 support split-supply operation?
Yes-the TLV2470CDRG4 operates with split supplies from ±1.35V to ±3V, as specified in the Recommended Operating Conditions table. Its rail-to-rail input range (VICR = –VS to +VS) and output swing (within 180mV of each rail) remain fully functional in dual-supply configurations, enabling bipolar signal handling in audio or instrumentation front-ends.
What is the turn-on time for the TLV2470CDRG4 after asserting the SHDN pin high?
The TLV2470CDRG4 has a typical turn-on time (ton) of 5μs, defined as the interval between SHDN rising past 2V and supply current reaching 50% of its active-state value (600μA), per Electrical Characteristics Table (page 6). This enables rapid wake-up in event-triggered sensing systems without sacrificing power savings.
Can the TLV2470CDRG4 drive a 600Ω load at 2.8MHz?
No-the TLV2470CDRG4's gain-bandwidth product of 2.8MHz is measured into a 600Ω load (per Gain-Bandwidth Product test condition on page 7), but full-power bandwidth into 600Ω is limited by slew rate (1.5 V/μs at 5V). At 2.8MHz, maximum undistorted output is ~0.85VPP; for full 3VPP swing, bandwidth must be reduced to ≤1.1MHz.
Is the TLV2470CDRG4 pin-compatible with other members of the TLV247x family?
No-TLV2470CDRG4 uses a SOT-23-6 pinout (OUT, IN−, IN+, GND, SHDN, VDD), while TLV2471CDR (SOT-23-5) omits SHDN and relocates GND, and TLV2472/3 use MSOP-8/10 with different pin assignments. PCB layout must be specific to TLV2470CDRG4; no mechanical or electrical drop-in replacement exists within the family.
