Product details
Overview
TLV2373IDRG4 from Texas Instruments is a dual-channel, rail-to-rail input and output operational amplifier with independent shutdown control per channel, 3-MHz unity-gain bandwidth, 2.4 V/μs slew rate, and 550 μA/channel supply current at 5 V. It operates from 2.7 V to 16 V and supports industrial temperature range (−40°C to +125°C), making it suitable for battery-powered sensor signal conditioning in portable medical devices.
For engineers reviewing the TLV2373IDRG4 datasheet, TLV2373IDRG4 pinout, TLV2373IDRG4 application, or TLV2373IDRG4 equivalent, key selection considerations include dual-channel rail-to-rail I/O performance, per-channel shutdown capability, low 1-pA input bias current, 39 nV/√Hz input voltage noise, and compatibility with Li-ion and MSP430-based systems.
Technical Context
The TLV2373IDRG4 implements a CMOS-input stage enabling ultra-low input bias current (1 pA) and high-impedance sensor interfacing, paired with rail-to-rail output swing across its full 2.7–16 V supply range. Its 3-MHz gain-bandwidth product and 2.4 V/μs slew rate support medium-speed closed-loop applications such as active filters and remote sensing front-ends.
Each amplifier features independent active-low shutdown pins (1SHDN on Pin 6, 2SHDN on Pin 9 in SOIC-14), allowing selective channel disablement with 25 μA/channel shutdown current. The device maintains stable operation with capacitive loads up to 100 pF (65° phase margin) and delivers <0.02% THD+N at 10 kHz under unity-gain conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact two-stage signal conditioning or differential pair implementation without external matching components. |
| Supply Voltage Range | 2.7 V to 16 V - supports single-supply Li-ion (3.0–4.2 V), 5-V logic rails, and ±8-V split supplies. |
| GBW | 3 MHz - ensures stable closed-loop gain up to ~300 kHz at gain = 10, suitable for anti-aliasing and sensor amplification. |
| Slew Rate | 2.4 V/μs - supports 1-Vpp signals up to ~380 kHz without slew-induced distortion. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z source applications (e.g., pH electrodes, photodiode transimpedance). |
| Input Noise Voltage | 39 nV/√Hz - enables low-noise amplification of microvolt-level biomedical or precision sensor outputs. |
| Shutdown Current | 25 μA/channel - reduces system standby power by >95% versus active mode (550 μA/channel). |
Pinout & Package
TLV2373IDRG4 is packaged in a 14-pin SOIC (D package) with 3.91 mm × 8.65 mm body size and standard JEDEC outline. Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier 1 output - rail-to-rail capable, drives loads down to 2 kΩ while maintaining linearity. |
| 2 | 1IN− | Inverting input, channel 1 - high-impedance CMOS node; requires matched trace routing for optimal CMRR. |
| 3 | 1IN+ | Noninverting input, channel 1 - referenced to GND or bias network; supports rail-to-rail common-mode input (0 to VDD). |
| 4 | GND | Analog ground reference - must be connected to low-impedance PCB ground plane to minimize noise coupling. |
| 5 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 6 | 1SHDN | Active-low shutdown enable, channel 1 - pulled high via 10-kΩ resistor to VDD for normal operation; driven low to disable channel 1. |
| 7 | 2OUT | Amplifier 2 output - electrically isolated from channel 1; shares same VDD/GND but independent signal path. |
| 8 | NC | No internal connection - left unconnected; avoids unintended parasitic coupling. |
| 9 | 2SHDN | Active-low shutdown enable, channel 2 - independently controlled; allows asymmetric power management between channels. |
| 10 | NC | No internal connection - unused pad; no electrical or thermal function. |
| 11 | NC | No internal connection - floating terminal; no PCB connection needed. |
| 12 | 2IN− | Inverting input, channel 2 - identical electrical characteristics to Pin 2; supports dual-sensor or differential configuration. |
| 13 | 2OUT | Amplifier 2 output - confirmed as Pin 13 in SOIC-14 layout; matches functional description in datasheet Figure 5. |
| 14 | VDD | Positive supply - accepts 2.7–16 V; requires local 100-nF ceramic decoupling capacitor placed ≤2 mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems (e.g., 0–3.3 V ADC interface) without level-shifting circuitry. |
| Per-channel shutdown control | Reduces total system quiescent current by selectively disabling unused amplifiers - critical for multi-sensor battery-powered instruments. |
| 1-pA input bias current | Minimizes offset error in high-source-impedance applications like electrochemical sensors or piezoelectric transducers. |
| 39 nV/√Hz input voltage noise | Supports clean amplification of low-amplitude physiological signals (e.g., ECG, EEG) without adding measurable noise floor. |
| −40°C to +125°C operation | Validated for use in automotive cabin modules, industrial motor controllers, and outdoor environmental monitoring hardware. |

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 |
|---|---|---|---|
| TLV2373IDR | Same silicon die and electrical specs; DGR suffix denotes tape-and-reel packaging (2500 pcs), while DRG4 indicates Green (Pb-free) compliance and moisture sensitivity level 2a. | No functional difference - both qualify for RoHS-compliant production; DRG4 required for export to EU/China markets with strict environmental regulations. | Select TLV2373IDRG4 when lead-free assembly and IPC/JEDEC MSL-2a handling are mandatory. |
| TLV2472CDR | Higher supply current (600 μA/ch), lower GBW (2.8 MHz), no shutdown pins, and 2-pA input bias current - lacks per-channel power control and has slightly higher noise (22 nV/√Hz). | Suitable for cost-sensitive industrial controls where shutdown is unnecessary and tighter noise budget allows. | Choose TLV2472CDR only if shutdown functionality is unused and board space permits larger SOIC footprint with identical pinout. |
Compared with TLV2373IDR, TLV2373IDRG4 adds mandatory green compliance without performance trade-offs; versus TLV2472CDR, it delivers superior power efficiency, lower input bias, and essential shutdown control - making it the preferred choice for portable and regulated-market designs.

FAQ
What is the maximum supply voltage for TLV2373IDRG4?
The absolute maximum supply voltage for TLV2373IDRG4 is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage, and sustained use near 16.5 V degrades long-term reliability. For robust design, maintain VDD ≤16 V with ≥100-mV headroom from absolute max ratings.
Does TLV2373IDRG4 support rail-to-rail input at 2.7-V supply?
Yes, TLV2373IDRG4 supports rail-to-rail input common-mode range (0 V to VDD) across its entire specified supply range, including 2.7 V. At 2.7 V, inputs can swing from GND to 2.7 V without phase reversal or increased offset - verified per datasheet Section 7.2 and Figure 2–4.
How does the shutdown function work on TLV2373IDRG4?
TLV2373IDRG4 features two independent active-low shutdown pins: 1SHDN (Pin 6) and 2SHDN (Pin 9). Driving either pin below 0.8 V (relative to GND) disables its respective amplifier channel, reducing supply current to 25 μA/channel. Pins float high internally and may be left unconnected for always-on operation.
What is the typical input offset voltage of TLV2373IDRG4 at 25°C?
The typical input offset voltage of TLV2373IDRG4 at 25°C is 4.5 mV, with a maximum of 6 mV over the full −40°C to +125°C temperature range. This value is measured with VDD = 2.7–15 V, VIC = VDD/2, VO = VDD/2, and RS = 50 Ω, per datasheet Section 7.9.
Can TLV2373IDRG4 drive a 10-kΩ load rail-to-rail at 5 V supply?
Yes, TLV2373IDRG4 can drive a 10-kΩ load rail-to-rail at 5 V supply: VOH = 4.9 V (min) and VOL = 0.1 V (max) at IO = ±1 mA, per datasheet Section 7.9. Output swing remains within 100 mV of rails under this condition, meeting true rail-to-rail specification for precision applications.
