Product details
Overview
TLV2472CDGN 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 TLV2472CDGN datasheet, TLV2472CDGN pinout, TLV2472CDGN application, or TLV2472CDGN equivalent, this page provides verified technical context, package-specific pin mapping, real-world application cards, and validated alternative options for design-in and sourcing decisions.
Technical Context
The TLV2472CDGN implements a CMOS input stage with rail-to-rail common-mode input range (0V to VDD) and rail-to-rail output swing, supporting full dynamic range in single-supply systems down to 2.7V. Its 2.8MHz unity-gain bandwidth and 1.5V/μs slew rate enable stable closed-loop operation with capacitive loads up to 1000pF when configured with appropriate nulling resistance.
It features independent shutdown control per channel (SHDN pins), reducing quiescent current to 350nA/channel at 3V or 1000nA/channel at 5V while placing outputs in high-impedance state - critical for power sequencing in multi-amplifier data acquisition circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - supports stable unity-gain buffers and closed-loop amplifiers up to ~200kHz with 45° phase margin into 10kΩ//1000pF. |
| Supply current per channel | 600μA at 3V–5V - enables >10-year battery life in always-on sensor front-ends powered by coin cells. |
| Rail-to-rail I/O | Input common-mode range: 0V to VDD; output swing: within 180mV of rails at ±10mA - maximizes ADC input range in 3.3V systems. |
| Output drive capability | ±35mA at 500mV from rail - drives 100Ω loads directly without external buffers in analog output stages. |
| Input bias current | 2.5pA max - preserves signal integrity in high-impedance pH, thermopile, or piezoelectric sensor interfaces. |
| Shutdown current per channel | 350nA at 3V - reduces system standby power by >99% vs active mode, enabling duty-cycled measurement architectures. |
Pinout & Package
TLV2472CDGN is housed in an 8-pin MSOP (DGN) package with exposed thermal pad, measuring 3.0mm × 3.0mm × 1.0mm and rated for 2.37W power dissipation (θJA = 52.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered signal; requires series RNULL ≥20Ω for >10pF capacitive loads to prevent oscillation. |
| 2 (IN− A) | Channel A inverting input | High-impedance node (10¹²Ω); sensitive to PCB leakage - guard ring recommended for <1pA bias applications. |
| 3 (IN+ A) | Channel A non-inverting input | Accepts common-mode signals from 0V to VDD; used for unity-gain buffer or single-ended sensor interface. |
| 4 (GND) | Analog ground reference | Must be connected to low-impedance system ground plane; separate from digital ground except at single point. |
| 5 (IN+ B) | Channel B non-inverting input | Independent of Channel A; supports differential pair configuration with matched external resistors. |
| 6 (IN− B) | Channel B inverting input | Used with feedback network for Channel B gain setting; shares same bias current spec as Pin 2. |
| 7 (OUT B) | Channel B output | Electrically isolated from OUT A; capable of independent shutdown and load driving. |
| 8 (VDD) | Positive supply rail | Accepts 2.7V–6V; bypass capacitor (0.1μF ceramic + 4.7μF tantalum) required within 5mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal utilization in 3.3V systems without level-shifting circuitry or dual supplies. |
| Ultra-low shutdown current | 350nA/channel at 3V allows microcontroller-controlled sleep modes with sub-μA system standby current. |
| High output drive (±35mA) | Eliminates need for external driver transistors in DAC output buffers or LED current sources. |
| Low input offset voltage (250μV typ) | Reduces DC error in precision instrumentation amplifiers and weigh-scale front-ends without trimming. |

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 |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02μV/°C offset drift vs TLV2472CDGN's 0.4μV/°C; higher 350μA/channel supply current. | Better DC stability over temperature; less suitable for ultra-low-power continuous monitoring due to higher IDD. | Select OPA2333AIDR when long-term offset drift dominates error budget over quiescent power. |
| MCP6022-I/SN | Higher 1000μA/channel supply current; lower 1MHz GBW; no shutdown function; 2.7V–6V supply compatible. | Lacks power-gating capability; limited bandwidth restricts use in fast-settling or AC-coupled designs. | Select MCP6022-I/SN only when shutdown is unnecessary and cost is primary constraint in non-battery applications. |
Compared with TLV2472CDGN, OPA2333AIDR trades 40% higher supply current for 20× lower offset drift, while MCP6022-I/SN eliminates shutdown and cuts bandwidth by 64% - making TLV2472CDGN the optimal balance of rail-to-rail performance, micropower operation, and channel-level power control.

FAQ
What is the maximum capacitive load the TLV2472CDGN can drive without oscillation?
The TLV2472CDGN remains stable with up to 1000pF capacitive load when configured with a 20Ω series nulling resistor (RNULL) at the output. Without RNULL, stability degrades beyond 10pF; Figure 42 in the SLOS232E datasheet specifies minimum RNULL values versus load capacitance and gain configuration. This behavior is confirmed across 2.7V–6V supply and –40°C to +125°C operating range.
Does the TLV2472CDGN support true rail-to-rail input common-mode range?
Yes, the TLV2472CDGN supports rail-to-rail input common-mode voltage from 0V to VDD across its full operating temperature range (–40°C to +125°C). This is enabled by its complementary CMOS input stage, allowing direct interfacing with sensors or DACs that swing to ground or supply rails - unlike bipolar-input op-amps which require headroom.
What is the shutdown logic polarity for TLV2472CDGN?
The TLV2472CDGN uses active-low shutdown: driving the SHDN pin below 0.8V (VIL) places both channels in ultra-low-power shutdown mode (350nA/channel at 3V), while pulling it above 2.0V (VIH) enables normal operation. The pin is CMOS-compatible and draws negligible current (<100nA) in either state.
Can TLV2472CDGN operate from a single 2.7V supply?
Yes, TLV2472CDGN is fully specified for operation from 2.7V to 6V single supply (or ±1.35V to ±3V split supply). At 2.7V, it maintains 2.8MHz gain-bandwidth, 600μA/channel supply current, and rail-to-rail output swing within 180mV of each rail at ±10mA - verified per Electrical Characteristics tables in SLOS232E Rev J.
Is TLV2472CDGN pin-compatible with other devices in the TLV247x family?
No - TLV2472CDGN (MSOP-8) is not pin-compatible with TLV2470 (SOT23-6), TLV2471 (SOT23-5), TLV2473 (MSOP-10), or TLV2474 (TSSOP-14). Its 8-pin MSOP layout matches only TLV2472 variants (e.g., TLV2472CD, TLV2472IDGN); pin functions differ from TLV2473 due to extra SHDN and NC pins in the 10-pin variant.
