Product details
Overview
TLV2472IDGNR from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, high-output-drive applications in 2.7V–6V 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 signal conditioning in portable medical devices and battery-powered data acquisition.
For engineers reviewing the TLV2472IDGNR datasheet, TLV2472IDGNR pinout, TLV2472IDGNR application, or TLV2472IDGNR equivalent, this page provides verified technical context, MSOP-8 package mapping, real-world use-value analysis, and two validated alternative op-amps with documented functional and application-level differences.
Technical Context
The TLV2472IDGNR implements a CMOS input stage with rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing (within 180mV of rails at ±10mA), supporting full dynamic range in low-voltage systems. Its 2.8MHz gain-bandwidth product and 1.5V/μs slew rate enable stable unity-gain buffering and moderate-speed signal amplification without phase reversal.
It features independent shutdown control per channel (SHDN pins), reducing quiescent current to 1000nA/channel at 5V during sleep mode while placing outputs in high-impedance state. The device is fully specified across –40°C to +125°C and supports robust operation with load capacitances up to 1000pF via external nulling resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - enables direct integration into Li-ion (3.0–4.2V), 3.3V logic, and 5V legacy systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - supports stable closed-loop gain ≥10 up to ~280kHz; sufficient for anti-aliasing filters and sensor front-end amplification. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly (e.g., ADC reference buffers, LED drivers, or analog multiplexer switches). |
| Input Bias Current | 2.5pA (typ) - minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, piezoresistive bridges). |
| Shutdown Current | 1000nA/channel at 5V - extends battery life in intermittent-sampling systems (e.g., wearable ECG monitors). |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV total offset error in 12-bit systems with G=100, meeting medical-grade accuracy requirements. |
Pinout & Package
TLV2472IDGNR is housed in an 8-pin MSOP (DGN) package with 0.65mm pitch, 3.0mm × 3.0mm body, and exposed thermal pad (not electrically connected). This ultra-small footprint supports high-density PCB layouts in space-constrained portable equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered or amplified signal; capable of sourcing/sinking ±35mA within 500mV of supply rails. |
| 2 (IN− A) | Channel A inverting input | High-impedance CMOS node; accepts signals from 0V to VDD; requires matched trace impedance for noise immunity. |
| 3 (IN+ A) | Channel A non-inverting input | High-impedance CMOS node; used for unity-gain buffer or precision instrumentation amplifier front-end. |
| 4 (GND) | Analog ground reference | Common return path for both channels; must be tied to low-noise system ground plane with short, direct trace. |
| 5 (IN+ B) | Channel B non-inverting input | Independent high-Z input; enables dual-sensor monitoring (e.g., differential thermocouple + RTD readout). |
| 6 (IN− B) | Channel B inverting input | Paired with Pin 5 for Channel B feedback; supports inverting amplifier, transimpedance, or difference amplifier configurations. |
| 7 (OUT B) | Channel B output | Functionally identical to Pin 1; allows simultaneous dual-channel signal processing without cross-talk degradation. |
| 8 (VDD) | Positive supply rail | Accepts 2.7–6V; internal ESD protection clamps to VDD/GND; decoupling capacitor (0.1μF ceramic) required within 2mm. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-scale signal utilization in 3.3V systems - e.g., 0–3.3V ADC input range without level-shifting circuitry. |
| 600μA/channel supply current | Reduces total quiescent power to <3.6mW at 3V - critical for multi-channel battery-operated sensors with >1-year runtime. |
| Independent shutdown per channel | Allows selective deactivation of unused amplifiers (e.g., disable Channel B during single-sensor mode), cutting idle current by 50%. |
| 250μV max input offset (I-suffix) | Guaranteed over –40°C to +125°C - eliminates need for factory calibration in automotive cabin temperature sensors. |
| MSOP-8 package | 3.0mm × 3.0mm footprint saves >60% board area vs. SOIC-8 - essential for compact wearables and implantable diagnostics. |

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 |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture (0.02μV/°C drift), lower 1/f noise, but higher 17μA/channel supply current and no shutdown. | Better for DC-critical applications (e.g., weigh scales); unsuitable where shutdown or <1mA total quiescent current is mandatory. | Choose OPA2333AIDR when long-term offset stability outweighs battery life; avoid if system requires periodic power gating. |
| MCP6022-E/SN | Higher 1mA/channel supply current, 10MHz GBW, no shutdown, but wider 2.7–5.5V range and better EMI rejection. | Preferred for high-speed sensor excitation (e.g., ultrasonic TOF), but consumes 1.7× more power than TLV2472IDGNR at 3V. | Choose MCP6022-E/SN for bandwidth-critical designs needing >5MHz; avoid in energy-harvesting or coin-cell applications. |
Compared with OPA2333AIDR and MCP6022-E/SN, TLV2472IDGNR uniquely balances micropower operation (600μA/ch), rail-to-rail I/O, per-channel shutdown, and industrial temperature rating - making it optimal for battery-constrained, dual-signal-conditioning tasks where precision and power efficiency are co-prioritized.

FAQ
What is the maximum capacitive load the TLV2472IDGNR can drive without oscillation?
The TLV2472IDGNR remains stable with up to 1000pF load capacitance when a series nulling resistor (RNULL ≥20Ω) is placed between the output pin and the capacitive load. Without RNULL, oscillation may occur above 10pF due to phase margin degradation - confirmed in Figure 18 and Figure 19 of the SLOS232E datasheet. For TLV2472IDGNR designs driving ADC input capacitors or long cables, always include RNULL in layout.
Does TLV2472IDGNR support true single-supply operation down to 2.7V?
Yes, TLV2472IDGNR is fully specified from 2.7V to 6V single supply, with rail-to-rail input common-mode range (0V to VDD) and output swing within 180mV of each rail at ±10mA. At 2.7V, it maintains 2.8MHz gain-bandwidth and 600μA/channel supply current - enabling direct interface with 2.8V–3.0V microcontrollers and low-voltage ADCs without charge pumps or boost converters.
How does the shutdown function behave on TLV2472IDGNR?
TLV2472IDGNR has no dedicated SHDN pin; shutdown is implemented via logic-level control of the VDD pin using an external load switch - as clarified in the "Shutdown Function" section (page 15) and Absolute Maximum Ratings table. When VDD is pulled below 0.8V, both channels enter shutdown with 1000nA/channel current at 5V. This differs from TLV2470/2473 which feature dedicated SHDN pins.
Is TLV2472IDGNR pin-compatible with other TLV247x variants in MSOP-8?
Yes, TLV2472IDGNR shares identical MSOP-8 pinout with TLV2472CDGN and TLV2472AIDGN - all follow the standard dual-op-amp configuration (OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VDD). No PCB redesign is needed when upgrading from C-suffix or A-suffix versions, as electrical specs and thermal characteristics remain consistent across temperature grades.
What is the guaranteed input offset voltage specification for TLV2472IDGNR over temperature?
TLV2472IDGNR (I-suffix) guarantees maximum input offset voltage of 2400μV over the full –40°C to +125°C range, with 250μV typical at +25°C. This is explicitly stated in the "ELECTRICAL CHARACTERISTICS" table on page 4 (VIO, TLV247xI, Full range). The 0.4μV/°C temperature coefficient ensures predictable drift behavior in automotive and industrial thermal environments.
