Product details
Overview
TLV2373ID from Texas Instruments is a dual-channel, rail-to-rail input and output operational amplifier with shutdown control, operating from 2.7 V to 16 V supply, delivering 3 MHz bandwidth and 2.4 V/μs slew rate at 550 μA per channel. It supports industrial temperature range (−40°C to +125°C) and is used in battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the TLV2373ID datasheet, TLV2373ID pinout, TLV2373ID application, or TLV2373ID equivalent, key selection criteria include dual-channel rail-to-rail I/O performance, low-power shutdown (25 μA/channel), 1 pA input bias current, and compatibility with Li-ion and MSP430-based systems requiring precision analog front-ends.
Technical Context
The TLV2373ID implements CMOS input stage architecture enabling ultra-low input bias current (1 pA) and high-impedance sensor interfacing. Its rail-to-rail input common-mode range extends from GND to VDD, while rail-to-rail output swing supports full dynamic range utilization across the entire supply range.
It features independent active-low shutdown pins (1SHDN and 2SHDN) per channel, allowing selective power gating without affecting the other amplifier. The device maintains stable operation with capacitive loads up to 100 pF and achieves ≥65° phase margin under typical conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-supply Li-ion (3.0–4.2 V), dual-supply (±1.35 V to ±8 V), and industrial 12-V systems |
| Bandwidth (GBW) | 3 MHz - enables accurate amplification of signals up to ~300 kHz in unity-gain stable configurations |
| 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-impedance transducer interfaces (e.g., pH electrodes, photodiodes) |
| Shutdown Current | 25 μA/channel - reduces system standby power by >95% vs active mode (550 μA/channel) |
| Input Noise Voltage | 39 nV/√Hz - suitable for low-level signal amplification where thermal noise dominates |

| 2 | 1IN− | Inverting input, channel 1 - high-impedance CMOS node, 1 pA bias current |
| 3 | 1IN+ | Noninverting input, channel 1 - rail-to-rail common-mode range (GND to VDD) |

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 |
|---|---|---|---|
| TLV2472IDR | Higher supply current (600 μA/ch), lower GBW (2.8 MHz), no shutdown, 2 pA input bias | Lacks per-channel shutdown; better DC precision but higher power | Choose when shutdown is unnecessary and offset drift (<0.5 µV/°C) is critical |
| OPA2333AIDR | Zero-drift architecture, 17 µV max VOS, 0.02 µV/°C drift, 350 µA/ch, no shutdown | No shutdown function; superior DC accuracy but narrower supply range (1.8–5.5 V) | Choose for ultra-low-offset applications powered from 3.3-V rails where shutdown is managed externally |
Compared with TLV2373ID, TLV2472IDR trades shutdown capability for slightly better DC specs and lower cost, while OPA2333AIDR offers zero-drift performance at the expense of supply flexibility and power gating-making TLV2373ID optimal for battery-constrained, wide-supply, multi-channel systems requiring independent power control.

FAQ
What is the maximum recommended supply voltage for TLV2373ID?
The maximum recommended supply voltage for TLV2373ID is 16 V, as specified in the Recommended Operating Conditions table. Absolute maximum rating is 16.5 V, but sustained operation above 16 V risks reliability degradation. This allows use with ±8-V split supplies or single 12-V/15-V industrial rails while preserving 3-MHz bandwidth and rail-to-rail output swing.
Does TLV2373ID support true rail-to-rail input common-mode range?
Yes, TLV2373ID supports rail-to-rail input common-mode voltage range from GND to VDD, verified across −40°C to +125°C. This enables direct interfacing with sensors whose output spans the full supply range (e.g., bridge sensors, resistive thermometers) without external level-shifting components, reducing BOM count and layout complexity.
How does the shutdown feature operate on TLV2373ID?
TLV2373ID has two independent active-low shutdown pins: 1SHDN (pin 6) and 2SHDN (pin 9). Driving either pin ≤0.8 V disables its respective amplifier channel, reducing supply current to 25 μA/channel. Leaving the pin floating or pulling it ≥2 V keeps the channel active. Shutdown recovery time is 0.8 μs, enabling rapid wake-up in duty-cycled systems.
Can TLV2373ID drive capacitive loads reliably?
Yes, TLV2373ID maintains stability with capacitive loads up to 100 pF, as confirmed by phase margin ≥65° in the Typical Characteristics section. For loads >100 pF, an isolation resistor (10–100 Ω) in series with the output is recommended to preserve stability without degrading small-signal bandwidth below 1 MHz.
What is the input bias current specification for TLV2373ID over temperature?
TLV2373ID specifies input bias current of 1 pA at 25°C, rising to ≤100 pA at +70°C and ≤1000 pA at +125°C, per Electrical Characteristics table. This ultra-low bias enables high-accuracy amplification of nanoamp-level sensor currents (e.g., photodiodes, ion-selective electrodes) without significant input error voltage across typical source impedances.
