Product details
Overview
TLV2471AIDR from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, high-output-drive applications. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage across 2.7V–6V supply range - ideal for precision sensor signal conditioning in battery-powered medical devices.
For engineers reviewing the TLV2471AIDR datasheet, TLV2471AIDR pinout, TLV2471AIDR application, or TLV2471AIDR equivalent, this page provides verified circuit role, validated SOT23-5 package mapping, confirmed shutdown behavior (1000nA/ch @ 5V), rail-to-rail I/O performance metrics, and two functionally comparable alternatives with documented parameter trade-offs.
Technical Context
The TLV2471AIDR 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 supports true rail-to-rail swing - delivering ±10mA within 180mV of each rail and ±35mA at 500mV off-rail - resolving key limitations of legacy micropower op-amps in low-voltage data acquisition.
It features an active-high shutdown control (SHDN) that places outputs in high-impedance state and reduces supply current to 1000nA/channel at 5V. Fully specified over –40°C to +125°C, it maintains 2.8MHz GBW and 1.5V/μs slew rate across 2.7V–6V operation without external compensation.
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 ≥10 up to ~280kHz with adequate phase margin. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly, eliminating need for external buffer stages. |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV error in 2V full-scale 12-bit ADC front-ends without trimming. |
| Supply Current per Channel | 600μA - allows >1000 hours of continuous operation on a 600mAh coin cell in portable instrumentation. |
| Shutdown Current | 1000nA at 5V - reduces quiescent power to 5nW, critical for wake-on-event sensor nodes. |
| Input Bias Current | 2.5pA - preserves signal integrity in high-impedance pH or photodiode transimpedance circuits. |
Pinout & Package
SOT23-5 package: 2.9mm × 1.6mm × 1.1mm body, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Delivers rail-to-rail voltage swing; capable of ±35mA into 500mV headroom. |
| 2 (IN−) | Inverting Input | High-impedance CMOS node; 2.5pA bias current enables high-Z feedback networks. |
| 3 (IN+) | Non-inverting Input | Rail-to-rail common-mode range (0V to VDD); accepts signals directly from resistive sensors. |
| 4 (GND) | Analog Ground Reference | Return path for input bias currents and output load; must be low-impedance for noise immunity. |
| 5 (VDD) | Positive Supply Rail | Accepts 2.7V–6V; internal regulation ensures stable biasing across full voltage range. |

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 supply current (550μA vs 600μA), higher output drive (±90mA), but no shutdown function. | Lacks SHDN pin - unsuitable for duty-cycled sensor nodes requiring deep sleep modes. | Select when maximum output current is required and shutdown is not needed. |
| OPA333AIDBVR | Zero-drift architecture, 10μV max VIO, 17μA supply current, no shutdown, 350kHz GBW. | Superior DC precision but lower bandwidth - trades AC performance for ultra-low offset drift. | Select for high-accuracy DC-coupled measurements where 2.8MHz bandwidth is unnecessary. |
Compared with TLV2471AIDR, TLV2461CDR offers greater output current but forfeits shutdown capability, while OPA333AIDBVR delivers microvolt-level offset stability at the cost of bandwidth and power efficiency - making TLV2471AIDR the optimal balance for rail-to-rail, low-power, medium-speed signal chains.

FAQ
What is the maximum output current capability of the TLV2471AIDR?
The TLV2471AIDR delivers ±35mA output current when the output is within 500mV of either supply rail, and ±10mA when within 180mV of the rails. This high drive strength allows direct interfacing with low-impedance loads such as LEDs, relays, or analog switches without external buffers - a key differentiator versus standard micropower op-amps. The TLV2471AIDR maintains this performance across its full 2.7V–6V supply range.
Does the TLV2471AIDR include a shutdown feature?
No - the TLV2471AIDR does not include a shutdown pin. Among the TLV247x family, only TLV2470, TLV2473, and TLV2475 offer shutdown functionality. The TLV2471AIDR is the single-channel variant without SHDN; its pinout (SOT23-5) contains only OUT, IN−, IN+, GND, and VDD. For shutdown capability in a single-channel SOT23 package, TI recommends TLV2470AIDR instead.
What is the input offset voltage specification for TLV2471AIDR over temperature?
The TLV2471AIDR has a typical input offset voltage of 250μV at +25°C, with a maximum of 1600μV over the full –40°C to +125°C industrial temperature range. Its temperature coefficient is 0.4μV/°C, meaning offset drift remains tightly bounded - for example, contributing less than 60μV additional error across a 150°C span. This performance is documented in the "TLV247xA" grade section of the official SLOS232E datasheet.
Can TLV2471AIDR drive capacitive loads, and what is the recommended isolation resistor value?
Yes, the TLV2471AIDR can drive capacitive loads, but stability requires external isolation. For loads >10pF, TI recommends placing a series resistor (RNULL) between the output and load. Values of 20Ω to 100Ω are effective - 20Ω works well for most applications, while higher values improve phase margin at the expense of small-signal settling time. This guidance is explicitly provided in Figure 42 and Section "Driving a Capacitive Load" of the TLV247x datasheet.
What package type and footprint does TLV2471AIDR use?
The TLV2471AIDR uses the SOT23-5 package: a 5-pin, surface-mount, plastic small-outline transistor package measuring 2.9mm × 1.6mm × 1.1mm. Pin 1 is marked by a beveled edge or molded dot; the pinout is OUT–IN−–IN+–GND–VDD (top view). This compact footprint supports high-density PCB layouts in portable and IoT devices, and is compatible with standard SMT assembly processes including reflow and wave soldering.
