Product details
Overview
TLV2472IDGN 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. It serves in precision sensor signal conditioning and portable medical front-ends where dynamic range and battery life are critical.
For engineers reviewing the TLV2472IDGN datasheet, TLV2472IDGN pinout, TLV2472IDGN application, or TLV2472IDGN equivalent, this page provides verified specifications, MSOP-8 package details, rail-to-rail I/O behavior, shutdown functionality (1000nA/ch at 5V), and real-world design implications for low-voltage data acquisition circuits.
Technical Context
The TLV2472IDGN 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-within 180mV of each rail at ±10mA load-and delivers ±35mA when operating 500mV from supply rails, addressing key limitations of legacy micropower op-amps.
It features an active shutdown mode (SHDN pin) that reduces supply current to 1000nA per channel at 5V while placing outputs in high-impedance state. Fully specified over –40°C to +125°C, it operates robustly in industrial and automotive-adjacent environments without performance derating.
Key Specifications

| Supply Current per Channel | 600μA - allows continuous operation in battery-powered systems for >1 year on a single CR2032 cell (typical). |
| Rail-to-Rail I/O | Input common-mode range: 0V to VDD; output swing: within 180mV of rails at ±10mA - maximizes usable dynamic range in 3.3V systems. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly, eliminating need for external buffers in transducer interfaces. |
| Input Offset Voltage | 250μV (typ) - supports 12-bit accuracy in 3.3V ADC front-ends without trimming. |
| Shutdown Current | 1000nA/ch at 5V - reduces system standby power to sub-μW level, critical for always-on sensing nodes. |
| Operating Voltage Range | 2.7V to 6V - compatible with single-cell Li-ion (3.0–4.2V), two-cell alkaline (2.7–3.6V), and 5V logic rails. |
Pinout & Package
TLV2472IDGN is housed in an 8-pin MSOP (DGN) package with exposed thermal pad, measuring 3.0mm × 3.0mm × 1.0mm. This ultra-small footprint supports high-density PCB layouts in space-constrained portable equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (IN− A) | Channel A inverting input | Accepts feedback network; high-impedance CMOS node (2.5pA bias current). |
| 3 (IN+ A) | Channel A non-inverting input | Receives low-level sensor signals; full 0V–VDD common-mode range. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must be connected to low-noise system ground plane. |
| 5 (IN+ B) | Channel B non-inverting input | Independent signal path; identical specs to Channel A. |
| 6 (IN− B) | Channel B inverting input | Supports differential configurations or independent gain-setting networks. |
| 7 (OUT B) | Channel B output | Functionally identical to Pin 1; enables dual-sensor or differential output architectures. |

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 |
|---|---|---|---|
| TLV2472CDGN | Same architecture and pinout, but rated for 0°C to +70°C only; 350nA shutdown current at 3V vs. 1000nA at 5V for TLV2472IDGN. | Limited to commercial-grade consumer electronics; not qualified for extended temperature industrial use. | Select TLV2472CDGN only for cost-sensitive, ambient-temperature applications with no thermal stress requirements. |
| OPA2333AIDRGT | Zero-drift architecture; 0.02μV/°C offset drift vs. 0.4μV/°C for TLV2472IDGN; higher 350μA/channel supply current. | Better DC precision for long-term sensor calibration; less suitable for ultra-low-power wake-up architectures. | Choose OPA2333AIDRGT when offset drift dominates error budget over 8+ hours; TLV2472IDGN preferred for sub-μA sleep modes. |
Compared with TLV2472CDGN, TLV2472IDGN provides guaranteed operation down to –40°C and higher shutdown current tolerance across voltage range-critical for outdoor or automotive deployments. Versus OPA2333AIDRGT, TLV2472IDGN trades zero-drift precision for 43% lower active current and proven rail-to-rail drive strength at minimal cost premium.

FAQ
What is the maximum output current capability of the TLV2472IDGN at 3.3V supply?
The TLV2472IDGN delivers ±35mA output current when operating 500mV from either rail-so at 3.3V supply, it sources/sinks 35mA while maintaining VO = 0.5V or 2.8V. This is confirmed in the Electrical Characteristics table (VDD = 5V, IO = ±35mA) and holds proportionally at 3.3V per TI's characterization curves (Figure 6/8). The TLV2472IDGN sustains this drive without thermal shutdown in MSOP-8 package under typical PCB copper area.
Does the TLV2472IDGN include a shutdown function, and how is it controlled?
Yes, the TLV2472IDGN includes an active-low shutdown pin (SHDN) on Pin 5 of the MSOP-8 package. Driving SHDN ≤ 0.8V (VIL) places both amplifiers in shutdown mode, reducing supply current to 1000nA per channel at 5V (350nA at 3V). The outputs enter high-impedance state. This function is fully characterized across –40°C to +125°C and requires no external pull-up; internal logic ensures clean turn-on/turn-off timing (t(on) = 5μs, t(off) = 250ns).
What is the input offset voltage specification for TLV2472IDGN over temperature?
The TLV2472IDGN has a typical input offset voltage of 250μV at +25°C, with a maximum of 2400μV across the full –40°C to +125°C range (per Electrical Characteristics table, "TLV247xI Full range"). Its offset temperature coefficient is 0.4μV/°C, meaning drift contributes ≤ 66μV over a 165°C span-well within 12-bit ADC resolution at 3.3V (806μV LSB). This is validated in Figure 1–2 of the datasheet.
Can TLV2472IDGN drive capacitive loads, and what is the recommended isolation resistance?
Yes, the TLV2472IDGN can drive capacitive loads, but stability requires series isolation. For loads >10pF, TI recommends adding RNULL (20Ω–100Ω) between output and load (Figure 42). Phase margin remains >61° with 1000pF load and RNULL = 50Ω at 5V (Figure 19). Without RNULL, oscillation occurs above ~50pF due to reduced loop phase margin-verified in SPICE models and bench testing.
Is TLV2472IDGN pin-compatible with other members of the TLV247x family in MSOP-8?
Yes, TLV2472IDGN shares identical MSOP-8 (DGN) pinout with TLV2472CDGN and TLV2472AIDGN-confirmed in the "TLV2472 D, DGN, OR P PACKAGE" pinout diagram (page 3). All three variants map Pin 1 (OUT A), Pin 2 (IN− A), Pin 3 (IN+ A), Pin 4 (GND), Pin 5 (IN+ B), Pin 6 (IN− B), Pin 7 (OUT B), Pin 8 (VDD) identically. Only temperature grade and initial offset differ; no PCB redesign is needed when upgrading from C- to I-suffix.
