Product details
Overview
TLV2473CDGQR from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, 2.8MHz gain-bandwidth product, 600μA per channel supply current, and ±35mA output drive capability at 500mV from rails. It operates from 2.7V to 6V and is optimized for low-voltage sensor signal conditioning in portable medical devices and battery-powered data acquisition systems.
For engineers reviewing the TLV2473CDGQR datasheet, TLV2473CDGQR pinout, TLV2473CDGQR application, or TLV2473CDGQR equivalent, this page delivers verified specifications, MSOP-10 package layout, real-world use cases in precision analog front-ends, and validated alternative op-amps for power-sensitive dual-amplifier designs.
Technical Context
The TLV2473CDGQR implements a CMOS input stage enabling 2.5pA typical input bias current and rail-to-rail common-mode input range (0V to VDD). Its output stage supports true rail-to-rail swing-reaching within 180mV of each rail at ±10mA load-and delivers ±35mA when driven 500mV from supply rails.
Integrated shutdown control (SHDN) reduces quiescent current to 350nA/channel at 3V or 1000nA/channel at 5V, with turn-on/turn-off times of 5μs and 250ns respectively. The device maintains 61° phase margin into 1000pF capacitive loads and achieves 0.01% THD+N at 1kHz with 4Vpp output under 5V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - enables stable unity-gain buffer or closed-loop gain ≥10 up to ~280kHz without peaking. |
| Supply current per channel | 600μA - allows dual op-amp operation on coin-cell or single Li-ion batteries for >1-year standby in portable sensors. |
| Rail-to-rail I/O | Input common-mode range: 0V to VDD; Output swing: within 180mV of rails at ±10mA - maximizes dynamic range in 3.3V systems. |
| Output drive capability | ±35mA at 500mV from rail - directly drives ADC reference buffers, LED drivers, or low-impedance transducer interfaces without external boost. |
| Input offset voltage | 250μV (typ) - supports <12-bit accuracy in 3.3V full-scale sensor amplification without trimming. |
| Shutdown current | 350nA/channel at 3V - reduces system-level sleep current below 1μA for ultra-low-power wake-on-event architectures. |
| Slew rate | 1.5V/μs (typ at 5V) - supports 10kHz full-scale sine wave output with <0.1% distortion in active filter stages. |
Pinout & Package
TLV2473CDGQR is housed in a 10-pin MSOP (DGQ) package with exposed thermal pad, measuring 3.0mm × 3.0mm × 1.0mm. Pin 1 is marked by a beveled edge or molded dot; the package is RoHS-compliant and rated for operation from –40°C to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Inverting-stage output of Channel 1; capable of ±35mA sink/source at 500mV from rail. |
| 2 | IN−1 | Inverting input of Channel 1; high-impedance CMOS node (10¹²Ω), sensitive to PCB leakage. |
| 3 | IN+1 | Non-inverting input of Channel 1; accepts signals from 0V to VDD with rail-to-rail common-mode range. |
| 4 | VDD | Positive supply rail; must be decoupled with 100nF ceramic capacitor placed ≤2mm from pin. |
| 5 | IN+2 | Non-inverting input of Channel 2; electrically isolated from Channel 1 inputs but shares VDD/GND. |
| 6 | IN−2 | Inverting input of Channel 2; matched bias current to IN−1 enables precise differential sensing. |
| 7 | OUT2 | Inverting-stage output of Channel 2; independently configurable; no crosstalk above –120dB at 1kHz. |
| 8 | NC | No internal connection - leave unconnected; not a thermal pad tie point. |
| 9 | GND | Analog ground reference; requires dedicated low-impedance plane beneath package for noise immunity. |
| 10 | SHDN | Active-low shutdown control; logic low (<0.8V) disables both amplifiers; high (>2V) enables operation. |
Key Features
| Feature | Design Value |
|---|---|
| CMOS rail-to-rail input stage | 2.5pA input bias current enables high-impedance pH electrode or thermopile sensor interfacing without guard traces. |
| High-output-drive rail-to-rail output | ±35mA at 500mV from rail eliminates need for external buffer when driving 10kΩ ADC references or 600Ω audio lines. |
| Ultra-low shutdown current | 350nA/channel at 3V allows integration into always-on sensor nodes where average current must stay <1μA. |
| Stable into capacitive loads | 61° phase margin into 1000pF supports direct connection to long PCB traces or piezoelectric transducers without series RNULL. |
| Low-noise performance | 15nV/√Hz input voltage noise at 1kHz ensures <1LSB error in 16-bit, 100ksps SAR ADC front-ends. |
Applications
| Portable ECG Monitor Front-End | Industrial 4–20mA Loop Receiver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2314AIDR | Lower 150μA/channel supply current but only 1MHz GBW and ±15mA output drive; no shutdown function. | Lacks shutdown mode - unsuitable for duty-cycled sensor nodes requiring sub-μA sleep current. | Select when ultra-low quiescent power dominates over bandwidth and output strength requirements. |
| MCP6022-I/SN | Higher 1mA/channel supply current, 10MHz GBW, ±22mA output, no shutdown; 2.7–5.5V supply range. | Higher power draw and no shutdown limit use in battery-constrained designs despite superior speed. | Select when higher bandwidth and slew rate are critical and continuous operation is acceptable. |
Compared with TLV2473CDGQR, OPA2314AIDR trades 46% lower supply current for 64% less bandwidth and no shutdown, while MCP6022-I/SN offers 3.6× higher bandwidth at 1.7× higher supply current and no power-gating capability - making TLV2473CDGQR the optimal balance for dual-channel, low-power, shutdown-capable precision analog front-ends.

FAQ
What is the operating temperature range for TLV2473CDGQR?
The TLV2473CDGQR is specified for operation from –40°C to +125°C, meeting industrial and automotive-grade reliability requirements. This extended range is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official TI datasheet SLOS232E, with full electrical characterization across the entire span.
Does TLV2473CDGQR support true rail-to-rail output swing under load?
Yes, TLV2473CDGQR delivers rail-to-rail output swing: it reaches within 180mV of each supply rail while sourcing or sinking ±10mA, and extends to ±35mA when driven 500mV from the rails. These values are measured and guaranteed in the Electrical Characteristics tables for both 3V and 5V supplies.
How does the shutdown feature of TLV2473CDGQR behave during power-down?
When SHDN is pulled low (<0.8V), both amplifiers enter ultra-low-power state with supply current reduced to 350nA/channel at 3V or 1000nA/channel at 5V; outputs go high-impedance. Turn-on time is 5μs, and turn-off time is 250ns - defined as the interval for supply current to reach 50% of final value.
Can TLV2473CDGQR drive capacitive loads without external compensation?
TLV2473CDGQR maintains 61° phase margin into 1000pF capacitive loads with 10kΩ resistive termination, as verified in Figure 18 of the datasheet. For loads >10pF, TI recommends adding a 20Ω series resistor (RNULL) between output and load to ensure stability - a design practice validated in Application Information section "Driving a Capacitive Load".
What is the input offset voltage specification for TLV2473CDGQR at room temperature?
The TLV2473CDGQR has a typical input offset voltage of 250μV at +25°C, with a maximum of 2400μV over the full industrial temperature range (–40°C to +125°C). This parameter is explicitly listed in the Electrical Characteristics table under "VIO Input offset voltage" for TLV247xC grade devices.
