Product details
Overview
TLV2472CD from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive signal conditioning in single-supply systems. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage - enabling precision sensor interfacing and portable medical instrumentation.
For engineers reviewing the TLV2472CD datasheet, TLV2472CD pinout, TLV2472CD application, or TLV2472CD equivalent, this page provides verified package mapping (SOIC-8), confirmed shutdown functionality (SHDN pin active-low), rail-to-rail I/O behavior across 2.7V–6V operation, and real-world design implications for capacitive-load stability and power-sensitive layout.
Technical Context
The TLV2472CD employs a CMOS input stage with 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), enabling full-swing operation in 3V and 5V systems. Its output stage supports ±35mA sourcing/sinking while maintaining 180mV rail clearance under 10mA load - resolving a key limitation of legacy micropower op-amps.
It integrates an active-low shutdown control (pin 1) that reduces supply current to 350nA/channel at 3V or 1000nA/channel at 5V, with 5μs turn-on and 250ns turn-off times. The device is fully specified over 0°C to +70°C (C-suffix) and exhibits stable phase margin (>61°) with up to 1000pF capacitive load when properly compensated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct integration into Li-ion (3.7V nominal) and USB-powered (5V) systems without LDO pre-regulation. |
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer configurations up to ~2.5MHz and closed-loop amplification with bandwidth >1MHz at moderate gains. |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV error in 2V full-scale 12-bit ADC front-ends without trimming. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 10Ω loads directly (e.g., LED drivers, relay coils) or 10kΩ+ loads with full rail-to-rail swing. |
| Shutdown Current | 350nA/channel at 3V - extends battery life in intermittent-sampling applications (e.g., wearable biosensors) by reducing quiescent draw by >1700×. |
| Input Bias Current | 2.5pA - minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoelectric sensors) without requiring guard traces. |
| Common-Mode Input Range | 0V to VDD - accepts signals spanning entire supply, eliminating level-shifting circuitry in single-supply data acquisition. |
Pinout & Package
TLV2472CD is housed in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3mm × 6.2mm, 1.27mm pitch). Pin 1 is marked by a beveled edge or molded dot; pin numbering follows counterclockwise convention from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SHDN | Active-low shutdown control - tie to VDD for normal operation; pull to GND to enter ultra-low-power mode (350nA/ch). |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (10¹²Ω) compatible with microamp-level sensor outputs. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts common-mode voltages from 0V to VDD without phase reversal. |
| 4 | GND | Analog ground reference - must be connected to system ground plane with low-inductance path to minimize noise coupling. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1 inputs; shares same VDD/GND rails. |
| 6 | 2IN− | Inverting input of Channel 2 - identical electrical characteristics to Pin 2; supports independent dual-channel signal paths. |
| 7 | 2OUT | Output of Channel 2 - rail-to-rail capable (within 180mV of rails at 10mA); requires series resistor ≥20Ω for >10pF capacitive loads. |
| 8 | VDD | Positive supply - decoupling capacitor (0.1μF ceramic) required within 5mm of pin to suppress high-frequency supply noise. |
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 mapped directly to 0–3V ADC input without level shifters. |
| 600μA/channel supply current | Reduces total quiescent power to <1.2mW at 3V - suitable for always-on battery-powered nodes with multi-year runtime requirements. |
| 2.8MHz gain-bandwidth product | Supports closed-loop bandwidth >1MHz at gain=2 - sufficient for ECG front-end filtering, ultrasonic receiver amplification, and fast-settling DAC buffers. |
| ±35mA output drive at 500mV from rail | Eliminates need for external driver transistors in low-side LED control or analog multiplexer buffering applications. |
| 350nA/channel shutdown current | Permits duty-cycled operation in wireless sensor nodes - e.g., 1s active / 999s shutdown yields average current <1μA per channel. |
| SOIC-8 package with industry-standard footprint | Ensures drop-in compatibility with existing PCB layouts designed for TL072, LM358, or other D-package dual op-amps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CD | Higher 6.4MHz GBW but 550μA/channel supply current; no shutdown function; ±90mA output drive. | Better for wideband active filters or high-speed DAC buffering where shutdown is unnecessary. | Select TLV2462CD when bandwidth >4MHz is required and ultra-low shutdown current is not needed. |
| OPA2340UA | 2.8MHz GBW, 750μA/channel, rail-to-rail I/O, but only 20mA output drive and no shutdown pin. | Suitable for lower-current precision applications (e.g., photodiode TIA) where output drive is secondary. | Choose OPA2340UA when superior AC performance (lower noise, better THD+N) is prioritized over shutdown capability and output strength. |
Compared with TLV2472CD, TLV2462CD trades shutdown functionality for higher bandwidth and stronger output drive, while OPA2340UA offers improved noise performance at the cost of reduced output current and no power management - making TLV2472CD optimal for battery-constrained, dual-role signal chains requiring both precision and power gating.

FAQ
What is the operating temperature range for TLV2472CD?
The TLV2472CD is rated for 0°C to +70°C (C-suffix), as confirmed in the "TLV2472 AND TLV2473 AVAILABLE OPTIONS" table and absolute maximum ratings section. This commercial-grade temperature range aligns with consumer and industrial portable equipment use cases, and differs from the extended –40°C to +125°C range offered by the TLV2472ID variant.
Does TLV2472CD include a shutdown feature, and how is it controlled?
Yes, TLV2472CD includes an active-low shutdown pin (Pin 1, SHDN). When pulled to GND, it disables both amplifiers and reduces supply current to 350nA/channel at 3V or 1000nA/channel at 5V. The device resumes normal operation within 5μs after SHDN is returned to VDD, as verified in the Operating Characteristics table on page 5 of the datasheet.
What is the maximum capacitive load TLV2472CD can drive without instability?
TLV2472CD maintains stable operation with up to 1000pF capacitive load when configured as a unity-gain follower with RL = 10kΩ, as shown in Figure 18 and Figure 19 (phase margin >61° at 3V). For loads exceeding 10pF, TI recommends adding a series nulling resistor (RNULL ≥20Ω) between the output and capacitive load, per Figure 42 in the Application Information section.
How does TLV2472CD's rail-to-rail input stage improve system design?
TLV2472CD's rail-to-rail input allows common-mode voltages from 0V to VDD, eliminating the need for external level-shifting circuitry when interfacing with single-supply sensors (e.g., resistive bridges, thermistors, or MEMS accelerometers). This simplifies PCB layout, reduces component count, and avoids introducing offset or gain errors associated with bias networks.
Can TLV2472CD replace LM358 in existing designs?
TLV2472CD can replace LM358 in many low-voltage, low-power applications due to its SOIC-8 pinout compatibility, rail-to-rail I/O, and superior specs (2.8MHz vs 1MHz GBW, 600μA vs 700μA/channel, 250μV vs 2mV offset). However, LM358 lacks shutdown and cannot operate below 3V, so validation is required for supply voltage, output loading, and timing-critical circuits.
