Product details
Overview
TLV2470CDR 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. It operates from 2.7V to 6V and is optimized for low-power sensor signal conditioning in portable medical devices and battery-powered data acquisition systems.
For engineers reviewing the TLV2470CDR datasheet, TLV2470CDR pinout, TLV2470CDR application, or TLV2470CDR equivalent, this page provides verified electrical specifications, validated SOT23-6 terminal mapping, real-world use cases in precision analog front-ends, and two confirmed alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2470CDR implements a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD). Its output stage supports true rail-to-rail swing-reaching within 180mV of both supply rails under ±10mA load-and delivers ±35mA when driven 500mV from rails.
Shutdown mode reduces supply current to 350nA/channel at 3V (1000nA at 5V), with turn-on/turn-off times of 5μs and 250ns respectively. Phase margin remains stable ≥61° across 100pF–1nF capacitive loads when using recommended RNULL series resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - enables direct operation from single Li-ion or dual alkaline cells without regulation. |
| Gain-Bandwidth Product | 2.8MHz - supports stable closed-loop gain up to ~28 at 100kHz for anti-aliasing filter interfaces. |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV error in 2V full-scale 12-bit ADC driver applications. |
| Output Drive Capability | ±10mA at 180mV from rails - drives 10kΩ loads while maintaining rail-to-rail dynamic range. |
| Shutdown Current | 350nA/channel at 3V - extends battery life by >1000× vs active mode in intermittent-sampling systems. |
| Input Bias Current | 2.5pA - minimizes voltage error across high-impedance sensor sources (e.g., pH electrodes, photodiodes). |
| Slew Rate | 1.5V/μs (typ at 5V) - settles 2V step within 1.8μs at 0.01% for fast-settling instrumentation amplifiers. |
Pinout & Package
SOT23-6 package with moisture sensitivity level 1 (MSL-1), RoHS-compliant, rated for 0°C to +70°C operation. Pin 1 marked by beveled edge or molded dot.
| 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 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 input common-mode and output swing; must be low-impedance return path. |
| 5 (SHDN) | Active-low shutdown control | Drives amplifier into ultra-low-current state when pulled ≤0.8V; VIH ≥2V enables operation. |
| 6 (VDD) | Positive supply | Accepts 2.7–6V; decoupling capacitor (0.1μF) required within 5mm of pin for stability. |
Key Features
| Feature | Design Value |

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 VIO. | Lacks shutdown capability; better for always-on high-speed filtering but unsuitable for duty-cycled sensing. | Select when continuous high-bandwidth performance outweighs power savings from shutdown. |
| OPA333AIDBVR | Zero-drift architecture; 17μV max VIO; 17μA supply current; no shutdown; SC70-5 package. | Superior DC precision but lower 350kHz GBW; incompatible pinout; no rail-to-rail output swing. | Choose for ultra-low-offset DC-coupled applications where bandwidth <100kHz suffices and shutdown is not required. |
Compared with TLV2470CDR, TLV2461CDR trades shutdown functionality for higher speed and slightly lower offset, while OPA333AIDBVR abandons shutdown and rail-to-rail output to achieve microvolt-level offset stability-making TLV2470CDR the only option balancing precision, power gating, and single-supply usability in space-constrained portable designs.

FAQ
What is the maximum capacitive load the TLV2470CDR can drive without oscillation?
The TLV2470CDR remains stable with capacitive loads up to 10pF directly on the output. For loads exceeding 10pF-including ADC input capacitance or cable termination-the datasheet mandates a series RNULL resistor (≥20Ω) between the TLV2470CDR output and the load to maintain ≥61° phase margin. This is verified in Figure 42 and confirmed across temperature and supply voltage ranges.
Does the TLV2470CDR support true rail-to-rail output swing at full rated load current?
Yes. The TLV2470CDR delivers ±10mA output current while swinging to within 180mV of both VDD and GND rails, as specified in the "High Output Drive Capability" section. At lighter loads (≤2.5mA), it achieves even tighter rail margins (≤150mV), enabling full dynamic range utilization in 3.3V or 5V single-supply systems.
How does shutdown mode affect the output state of the TLV2470CDR?
When the SHDN pin is pulled low (≤0.8V), the TLV2470CDR places its output in a high-impedance state-neither sourcing nor sinking current-and reduces supply current to 350nA/channel at 3V. This prevents loading of downstream circuitry and eliminates DC error injection during sleep cycles, critical for multiplexed sensor arrays.
Can the TLV2470CDR operate from a 2.5V supply?
No. The absolute minimum supply voltage for the TLV2470CDR is 2.7V, as defined in the Recommended Operating Conditions table. Operation below 2.7V risks parametric noncompliance-including reduced output swing, increased input offset, and failure to meet shutdown current specs-and is outside guaranteed specifications.
Is the TLV2470CDR pin-compatible with other SOT23-6 op-amps like the TLV2371?
No. The TLV2470CDR uses a unique SOT23-6 pinout: OUT/IN−/IN+/GND/SHDN/VDD. In contrast, TLV2371 (SOT23-6) assigns pins as OUT/IN−/IN+/VDD/NC/GND-swapping GND and VDD positions and omitting shutdown. PCB layout must be dedicated to TLV2470CDR; no mechanical or electrical drop-in replacement exists.
