Product details
Overview
TLV2472IP from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for 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 - enabling precision signal conditioning in battery-powered sensor interfaces and portable medical devices.
For engineers reviewing the TLV2472IP datasheet, TLV2472IP pinout, TLV2472IP application, or TLV2472IP equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in TI's SLOS232E datasheet and official MSOP-8 packaging documentation.
Technical Context
The TLV2472IP operates as a dual-channel, single-supply op amp with fully rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 180mV of rails at 10mA load). Its CMOS input stage achieves 2.5pA typical input bias current and 250μV input offset voltage, supporting high-impedance source interfacing without significant error.
It features no internal shutdown control - unlike TLV2470/2473/2475 variants - confirmed by absence of SHDN pin in its MSOP-8 pinout and omission from shutdown current specs in the datasheet. The device is fully specified over –40°C to +125°C and supports stable operation into capacitive loads ≥10pF when using series nulling resistor (RNULL ≥20Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact two-stage amplification or differential signal processing in one 3mm × 3mm MSOP-8 package. |
| Supply Voltage Range | 2.7V to 6V - compatible with single-cell Li-ion (3.0–4.2V), 3.3V logic, and 5V systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - supports closed-loop gains up to ~28 at 100kHz, suitable for anti-aliasing filters and sensor front-end amplification. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 10kΩ loads to full scale while sourcing/sinking >3× typical micropower op amps. |
| Input Offset Voltage | 250μV (typ) - contributes <0.01% error in 2.5V full-scale measurements, critical for 12-bit+ data acquisition accuracy. |
| Supply Current per Channel | 600μA (typ at 5V) - enables continuous operation in always-on sensor nodes with multi-year battery life on coin cells. |
| Input Bias Current | 2.5pA (typ) - minimizes voltage error across high-value feedback networks (e.g., 10MΩ resistors add <25μV error). |
Pinout & Package
TLV2472IP is packaged in an 8-pin MSOP (DGN) with exposed thermal pad, measuring 3.0mm × 3.0mm × 1.0mm. This thermally enhanced package supports higher power dissipation than SOIC-8 and enables dense PCB layouts in space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Delivers rail-to-rail output swing; requires RNULL ≥20Ω for stable driving of >10pF capacitive loads. |
| 2 (IN−1) | Channel 1 inverting input | High-impedance CMOS node; sensitive to ESD - requires guarding and proper PCB layout per TI guidelines. |
| 3 (IN+1) | Channel 1 non-inverting input | Accepts input signals from 0V to VDD; used for unity-gain buffers or active filters with DC-coupled inputs. |
| 4 (VDD) | Positive supply | Must be bypassed with 0.1μF ceramic capacitor near pin; supports 2.7V–6V operation with 7V absolute max rating. |
| 5 (IN+2) | Channel 2 non-inverting input | Independent input for second channel; shares same VDD/GND rails - no cross-channel isolation beyond PSRR. |
| 6 (IN−2) | Channel 2 inverting input | Matches IN−1 electrical characteristics; enables matched dual instrumentation amplifier configurations. |
| 7 (OUT2) | Channel 2 output | Functionally identical to OUT1; supports independent loading and output filtering per channel. |
| 8 (GND) | Analog ground reference | Single ground pin for both channels; requires low-impedance connection to system AGND plane to minimize crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in low-voltage (≥2.7V) systems - e.g., 0–3.3V ADC interface without level shifters. |
| 600μA/channel ultra-low quiescent current | Reduces total system power by >50% vs. comparable 1mA/op-amp families - critical for multi-sensor IoT edge nodes. |
| ±35mA high output drive | Drives 10kΩ loads to rail while maintaining linearity - eliminates need for external buffer stages in transducer interfaces. |
| 2.5pA input bias current | Preserves signal integrity with high-impedance sources (e.g., pH electrodes, piezoelectric sensors) without added offset error. |
| 2.8MHz gain-bandwidth at low power | Supports bandwidth-critical functions like ECG lead filtering (150Hz BW) or ultrasonic receiver amplification (1MHz BW) within micropower envelope. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2472CDR | Same silicon, C-temp (0°C to +70°C), tape-and-reel packaging - no thermal or electrical performance difference. | Targeted at commercial-grade consumer electronics where extended temperature range is unnecessary. | Select TLV2472CDR for cost-sensitive volume production with ambient-only operating conditions. |
| OPA2340UA | Higher 5.5MHz GBW, 1.2mA/channel supply current, 10pA IIB - trades power for speed and lower noise (12nV/√Hz). | Better suited for higher-frequency sensor interfaces (e.g., ultrasonic flow meters) where 2.8MHz is limiting. | Choose OPA2340UA when bandwidth >4MHz is required and 2× supply current is acceptable. |
Compared with TLV2472IP, TLV2472CDR offers identical performance at lower cost for commercial environments, while OPA2340UA provides significantly higher bandwidth and lower noise at doubled quiescent current - making TLV2472IP optimal for ultra-low-power, industrial-temperature dual-channel amplification where 2.8MHz suffices.

FAQ
Does TLV2472IP include a shutdown feature?
No, TLV2472IP does not have a shutdown function. Unlike TLV2470, TLV2473, or TLV2475 variants, the TLV2472IP lacks a SHDN pin and corresponding shutdown circuitry - confirmed by its 8-pin MSOP pinout (no dedicated shutdown terminal) and absence of IDD(SHDN) specifications in the datasheet for TLV2472 devices.
What is the maximum capacitive load TLV2472IP can drive stably?
TLV2472IP remains stable with capacitive loads up to 10pF when directly connected. For loads exceeding 10pF, TI recommends adding a series nulling resistor (RNULL ≥20Ω) between the output pin and the load - as documented in Figure 42 of the SLOS232E datasheet - to maintain phase margin above 60° and prevent oscillation.
Is TLV2472IP pin-compatible with other TLV247x variants in MSOP-8?
No, TLV2472IP is not pin-compatible with TLV2473IDGQ (10-pin MSOP) or TLV2470/2471 (SOT23-5/6). Within the MSOP-8 footprint, only TLV2472 variants (e.g., TLV2472CDR, TLV2472IDGN) share identical pinout - confirmed by the "TLV2472 D, DGN, OR P PACKAGE" diagram showing pins 1–8 as OUT1, IN−1, IN+1, VDD, IN+2, IN−2, OUT2, GND.
What is the input common-mode voltage range for TLV2472IP?
The input common-mode voltage range for TLV2472IP is 0V to VDD - fully rail-to-rail - allowing direct interfacing with sensors or DACs operating at the same supply rails. This is explicitly specified in the "RECOMMENDED OPERATING CONDITIONS" table of the SLOS232E datasheet under "Common-mode input voltage range, VICR".
Can TLV2472IP operate from a 2.5V supply?
No, TLV2472IP has a minimum recommended supply voltage of 2.7V per the "RECOMMENDED OPERATING CONDITIONS" table in the datasheet. Operation below 2.7V may result in degraded parameters including reduced output swing, increased input offset voltage, and unstable biasing - TI does not characterize or guarantee performance at 2.5V.
