Product details
Overview
TLV2373IDGSR 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 across 2.7–16 V operation. It operates from −40°C to +125°C and is used in battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the TLV2373IDGSR datasheet, TLV2373IDGSR pinout, TLV2373IDGSR application, or TLV2373IDGSR equivalent, key selection criteria include dual-channel RRIO performance at ultra-low quiescent current, independent channel shutdown capability, industrial temperature range support, and VSSOP-10 packaging for space-constrained analog front-ends.
Technical Context
The TLV2373IDGSR implements CMOS input stage architecture enabling 1 pA input bias current and rail-to-rail common-mode input range (0 V to VDD). Its dual-channel design features separate active-low shutdown pins (1SHDN on Pin 5, 2SHDN on Pin 6) allowing independent channel disable with 25 µA/channel shutdown current at 2.7–5 V.
It delivers 3 MHz gain-bandwidth product and 2.4 V/µs slew rate under 5 V supply while maintaining rail-to-rail output swing (within 150 mV of rails at 1 mA load), supporting precision closed-loop configurations in single-supply systems such as handheld test equipment and remote sensing nodes.

| 3 | 1IN+ | Noninverting input, channel 1 - accepts common-mode voltages from GND to VDD |
| 4 | GND | Analog ground reference - must be low-impedance connection to minimize noise coupling |
| 5 | 1SHDN | Active-low shutdown control for channel 1 - float or tie to VDD to enable; ≤0.8 V to disable |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel RRIO operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2472IDR | Lower GBW (2.8 MHz), higher supply current (600 µA/ch), no shutdown pins | Lacks independent channel shutdown; suited for always-on precision applications | Select when shutdown functionality is unnecessary and slightly lower bandwidth is acceptable |

FAQ
What is the maximum recommended supply voltage for TLV2373IDGSR?
The maximum recommended supply voltage for TLV2373IDGSR is 16 V, as specified in the Recommended Operating Conditions table. Absolute maximum rating is 16.5 V, but sustained operation above 16 V may impact reliability. This allows compatibility with ±8-V split supplies or high-cell-count battery stacks while maintaining 3-MHz bandwidth and rail-to-rail output swing.
Does TLV2373IDGSR support true rail-to-rail input and output?
Yes, TLV2373IDGSR supports true rail-to-rail input (common-mode range from GND to VDD) and rail-to-rail output (swing within 150 mV of rails at 1 mA load). This is confirmed in the Features section and Electrical Characteristics tables, enabling full utilization of supply voltage headroom in single-supply systems like 3.3-V microcontroller-based data loggers.
How does the shutdown function operate on TLV2373IDGSR?
TLV2373IDGSR has two independent active-low shutdown pins: 1SHDN (Pin 5) and 2SHDN (Pin 6). Driving either pin ≤0.8 V disables its respective amplifier channel, reducing supply current to 25 µA/channel. Pins can be left floating (default enabled) or tied to VDD. Turnon/turnoff times are 0.8 µs and 1 µs respectively, as measured into 2-kΩ load.
What is the input bias current specification for TLV2373IDGSR?
The input bias current for TLV2373IDGSR is 1 pA at 25°C, with a maximum of 1000 pA at +125°C. This ultra-low value is enabled by its CMOS input stage and is critical for preserving accuracy in high-impedance sensor interfaces such as pH probes and photodiode transimpedance amplifiers where leakage currents dominate error budgets.
Which package type is used by TLV2373IDGSR?
TLV2373IDGSR uses the DGSR designation, indicating a 10-pin VSSOP package (3.00 mm × 3.00 mm body, 0.5-mm lead pitch). This ultra-small outline package is documented in TI's orderable addendum and thermal tables, offering superior thermal resistance (RθJA = 166.5°C/W) compared to SOIC-14 alternatives while enabling high-density analog layout.
