Product details
Overview
TLV2373IDR 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), enabling use in battery-powered sensor front-ends and portable medical instrumentation.
For engineers reviewing the TLV2373IDR datasheet, TLV2373IDR pinout, TLV2373IDR application, or TLV2373IDR equivalent, key selection considerations include dual-channel rail-to-rail I/O performance, per-channel shutdown capability, low 1 pA input bias current for high-impedance sensing, and compatibility with Li-ion and MSP430-based systems requiring 2.7-V operation.
Technical Context
The TLV2373IDR implements a CMOS-input, rail-to-rail output stage optimized for single-supply operation down to 2.7 V while maintaining 3-MHz bandwidth and 2.4 V/µs slew rate. Its dual-channel architecture includes separate SHDN pins (pins 6 and 9 in SOIC-14) enabling independent channel enable/disable without affecting the other amplifier.
It features ultra-low input bias current (1 pA typ) and input offset voltage (4.5 mV max at 25°C), making it suitable for precision transducer interfaces. The device achieves rail-to-rail common-mode input range (0 V to VDD) and output swing within 150 mV of rails at 1 mA load, validated across −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports Li-ion (3.0–4.2 V), dual ±1.35 V to ±8 V, and wide industrial supplies |
| Bandwidth (UGBW) | 3 MHz - enables stable closed-loop gain up to ~100 at 30 kHz with adequate phase margin |
| Slew Rate | 2.4 V/µs - supports 1-Vpp signals up to ~380 kHz without slew-induced distortion |
| Input Bias Current | 1 pA (typ) - minimizes voltage error in high-Z sensor circuits (e.g., pH electrodes, photodiodes) |
| Shutdown Current | 25 µA/channel (typ at 5 V) - reduces system standby power by >95% vs active mode (550 µA) |
| Input Noise Voltage | 39 nV/√Hz - suitable for low-frequency precision amplification with <1 µVpp integrated noise in 10 kHz BW |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, automotive cabin, and white goods environments |
Pinout & Package
TLV2373IDR is packaged in a 14-pin SOIC (D package) with body size 8.65 mm × 3.91 mm. Pinout follows standard dual-opamp configuration with independent shutdown controls.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of channel 1 - rail-to-rail swing, capable of sourcing/sinking ≥7 mA at 5 V |
| 2 | 1IN− | Inverting input, channel 1 - high-impedance CMOS node (1 pA bias), accepts 0 V to VDD common-mode |
| 3 | 1IN+ | Noninverting input, channel 1 - identical specs to pin 2; differential pair input stage |
| 4 | GND | Analog ground reference - must be low-impedance connection shared with signal return paths |
| 6 | 1SHDN | Active-low shutdown control, channel 1 - logic-low (<0.8 V) disables channel 1 output and reduces IDD to 25 µA |
| 9 | 2SHDN | Active-low shutdown control, channel 2 - independent of pin 6; enables selective channel power gating |
| 11 | 2OUT | Output of channel 2 - electrically identical to pin 1; no crosstalk specification given but measured <−80 dB @ 10 kHz |
| 12 | 2IN− | Inverting input, channel 2 - isolated from channel 1 inputs; no internal coupling |
| 13 | 2OUT | Noninverting input, channel 2 - matches pin 3 functionality; supports differential or single-ended configurations |
| 14 | VDD | Positive supply - accepts 2.7–16 V; requires local 0.1-µF ceramic bypass capacitor to GND |
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 | Allows independent power management of each op-amp - critical for multi-sensor systems where only one channel is active at a time |
| 1 pA input bias current | Reduces voltage error in high-impedance feedback networks (>10 MΩ) and preserves accuracy in piezoelectric or electrochemical sensors |
| 3-MHz bandwidth at 550 µA | Delivers high-speed performance with micro-power quiescent current - 5.5× more bandwidth per µA than TLC227x family |
| −40°C to +125°C operation | Qualified for under-hood automotive, motor drive feedback, and industrial PLC modules without derating |

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 |
|---|---|---|---|
| TLV2373IPW | TSSOP-14 package (5.00 mm × 4.40 mm); 121 °C/W RθJA vs 67 °C/W for SOIC-14; identical electrical specs | Preferred for space-constrained PCBs; thermal performance less favorable in high-power-density layouts | Select TLV2373IPW when board area is constrained and airflow is limited; verify thermal rise under worst-case load. |
| TLV2472CDR | Higher supply current (600 µA/ch), lower bandwidth (2.8 MHz), no shutdown function; 2.5 mV VOS max | Lacks per-channel shutdown; better DC precision but higher static power; not drop-in compatible due to missing SHDN pins | Choose TLV2472CDR only if shutdown is unnecessary and VOS < 2.5 mV is mandatory; requires PCB redesign. |
Compared with TLV2373IPW and TLV2472CDR, TLV2373IDR offers optimal balance of thermal performance (67 °C/W), per-channel shutdown, and industry-standard SOIC footprint - making it the preferred choice for thermally demanding, power-aware industrial designs.

FAQ
What is the maximum supply voltage rating for TLV2373IDR?
The absolute maximum supply voltage for TLV2373IDR is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage. At 16 V, the device delivers full rail-to-rail output swing and maintains 3-MHz bandwidth, making it suitable for ±8-V split-supply equivalents or high-voltage battery monitoring.
Does TLV2373IDR support true rail-to-rail input at all supply voltages?
Yes, TLV2373IDR supports rail-to-rail input common-mode range (0 V to VDD) across its entire 2.7–16 V supply range and full −40°C to +125°C temperature range. This is confirmed in Section 7.2 of the datasheet under Recommended Operating Conditions, enabling direct interfacing with sensors whose output spans the full supply rail.
How does the shutdown function operate on TLV2373IDR?
TLV2373IDR has two independent active-low shutdown pins: 1SHDN (pin 6) and 2SHDN (pin 9). Driving either pin below 0.8 V (VOFF) disables its respective amplifier channel, reducing supply current to 25 µA/channel. Pins left floating default to active (enabled) state. Turnon/turnoff times are 0.8 µs and 1 µs respectively, per datasheet Section 7.9.
What is the typical input offset voltage of TLV2373IDR at room temperature?
The typical input offset voltage of TLV2373IDR 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 VIC = VDD/2 and VO = VDD/2, per Section 7.9 of the datasheet. Drift is specified at 2 µV/°C, supporting stable DC-coupled gain stages.
Can TLV2373IDR drive a 10-kΩ load while maintaining rail-to-rail output swing?
Yes, TLV2373IDR maintains rail-to-rail output swing into a 10-kΩ load. At 5 V supply and 25°C, VOH is 4.9 V (min) and VOL is 0.1 V (max) at 1 mA load - corresponding to <2% headroom from rails. Even at 5 mA load, VOH remains ≥4.6 V and VOL ≤0.4 V, confirming robust drive capability for standard ADC and comparator interfaces.
