Product details
Overview
TLV2375IDR from Texas Instruments is a quad rail-to-rail input/output operational amplifier with integrated shutdown control for channels 1–2 and 3–4. It delivers 3-MHz unity-gain bandwidth, 2.4-V/µs slew rate, 550-µA per-channel supply current at 5 V, and operates from 2.7 V to 16 V across −40°C to +125°C. It enables precision signal conditioning in battery-powered industrial sensors and portable medical devices.
For engineers reviewing the TLV2375IDR datasheet, TLV2375IDR pinout, TLV2375IDR application, or TLV2375IDR equivalent, key selection criteria include its dual-pair shutdown architecture, rail-to-rail output swing down to 2.7 V, low 1-pA input bias current, and guaranteed performance over extended temperature range - critical for high-impedance sensor front-ends and energy-constrained embedded systems.
Technical Context
The TLV2375IDR implements CMOS input stages enabling ultra-low input bias current (1 pA typical) and rail-to-rail common-mode input range (0 V to VDD). Its internal architecture supports independent shutdown of two channel pairs via dedicated 1/2SHDN and 3/4SHDN pins, each active-low with defined turnon/turnoff times (0.8 µs / 1.0 µs).
It achieves stable unity-gain operation with 65° phase margin into 100-pF capacitive loads and maintains 3-MHz bandwidth across 2.7–15 V supply range. Input offset voltage is specified at 4.5 mV (typ) and drifts only 2 µV/°C, supporting DC-coupled precision amplification without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single Li-ion (3.0–4.2 V), dual alkaline (3.0 V), or ±8-V split supplies. |
| Bandwidth (UGBW) | 3 MHz - enables accurate amplification of signals up to ~1.5 MHz at unity gain with <0.1% settling. |
| Slew Rate | 2.4 V/µs - supports full-scale 1-V step response in <0.42 µs, suitable for fast-sampling data acquisition. |
| Input Bias Current | 1 pA (typ) - minimizes voltage error in high-Z sensor interfaces (e.g., pH electrodes, photodiode transimpedance). |
| Shutdown Current | 25 µA/channel (typ at 5 V) - reduces total system quiescent power by >95% when channels are disabled. |
| Input Noise Voltage | 39 nV/√Hz at 1 kHz - ensures <1 µV RMS noise in 10-kHz bandwidth, critical for low-level analog signal integrity. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, automotive under-hood, and white goods motor control. |
Pinout & Package
TLV2375IDR is supplied in a 16-pin SOIC (D package) with body size 10.30 mm × 6.40 mm and standard 1.27-mm pitch. 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 swing (0.05 V to VDD − 0.08 V at 1 mA) enables direct interface to ADC inputs. |
| 2 | 1IN− | Inverting input, channel 1 - high-impedance CMOS node (1 pA bias) for precision differential sensing. |
| 3 | 1IN+ | Noninverting input, channel 1 - accepts common-mode voltages from 0 V to VDD, simplifying level-shifting design. |
| 4 | VDD | Positive supply - powers all four op-amps and shutdown logic; decoupling capacitor required at pin. |
| 5 | 2IN+ | Noninverting input, channel 2 - electrically isolated from channel 1 inputs to prevent crosstalk in multi-channel filtering. |
| 6 | 2IN− | Inverting input, channel 2 - matched to channel 1 for consistent gain accuracy in dual instrumentation configurations. |
| 7 | 2OUT | Amplifier 2 output - independently buffered; no shared output stage with channel 1. |
| 8 | 1/2SHDN | Active-low shutdown enable for channels 1 & 2 - floats high to enable; pulled low (<0.8 V) disables both amps. |
| 9 | 3/4SHDN | Active-low shutdown enable for channels 3 & 4 - independent control allows staggered power sequencing. |
| 10 | 3OUT | Amplifier 3 output - identical drive capability to channels 1–2; supports simultaneous multi-signal processing. |
| 11 | 3IN− | Inverting input, channel 3 - part of second pair optimized for same layout symmetry as first pair. |
| 12 | 3IN+ | Noninverting input, channel 3 - referenced to same GND as all channels; no internal isolation between pairs. |
| 13 | GND | Analog ground reference - must be low-impedance connection to minimize PSRR degradation and noise coupling. |
| 14 | 4IN− | Inverting input, channel 4 - completes quad configuration; pinout symmetry aids PCB routing in filter banks. |
| 15 | 4IN+ | Noninverting input, channel 4 - enables fully independent 4-channel signal paths without shared input nodes. |
| 16 | 4OUT | Amplifier 4 output - rail-to-rail swing matches other outputs; supports parallel driving of multiple loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464CDR | Higher supply current (725 µA/ch), no shutdown, rail-to-rail output only (not input), 6.4-MHz GBW. | Better AC performance but unsuitable for battery-powered shutdown use cases; requires higher supply headroom for input common-mode range. | Select when bandwidth >3 MHz is required and continuous operation is acceptable. |
| OPA4340UA | Lower noise (12 nV/√Hz), no shutdown, rail-to-rail output only, 5.5-MHz GBW, 750 µA/ch supply current. | Superior SNR for audio/precision measurement but lacks shutdown and rail-to-rail input - limits low-voltage sensor interfacing. | Select for high-fidelity signal chains where power efficiency is secondary to noise floor. |
Compared with TLV2464CDR and OPA4340UA, the TLV2375IDR uniquely combines rail-to-rail input/output, dual-pair shutdown, and sub-600-µA quiescent current - making it the only option among the three qualified for extended-life, low-voltage, multi-channel sensor systems requiring selective power gating.

FAQ
What is the maximum supply voltage for TLV2375IDR?
The absolute maximum supply voltage for TLV2375IDR 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 compatible with legacy ±8-V systems and modern high-voltage industrial rails. Always observe thermal limits - junction temperature must remain below 150°C.
Does TLV2375IDR support true rail-to-rail input?
Yes, TLV2375IDR supports true rail-to-rail input: its common-mode input voltage range extends from 0 V to VDD across the full temperature range (−40°C to +125°C). This is enabled by complementary CMOS input pairs, allowing direct interfacing with sensors or DACs that output near-ground or near-rail voltages without external level-shifting. Input offset voltage remains stable across this range, with typical drift of only 2 µV/°C.
How does the dual-pair shutdown function work on TLV2375IDR?
TLV2375IDR features two independent shutdown pins: pin 8 (1/2SHDN) controls channels 1 and 2, while pin 9 (3/4SHDN) controls channels 3 and 4. Each is active-low - pulling either pin below 0.8 V disables the corresponding pair, reducing supply current to 25 µA per channel. Both pins can float high to enable all channels. Turnon time is 0.8 µs; turnoff time is 1.0 µs. This architecture enables flexible power management in multi-sensor systems without cross-talk between enabled/disabled sections.
Can TLV2375IDR drive capacitive loads?
TLV2375IDR is stable driving up to 100 pF capacitive load with 65° phase margin, as verified in the datasheet's Figure 20. For loads >100 pF, external series resistance (typically 10–100 Ω) at the output is recommended to maintain stability. The device's unity-gain bandwidth (3 MHz) and slew rate (2.4 V/µs) ensure predictable settling behavior - e.g., 0.1% settling in 2.0 µs for a 1-V step with 47-pF load and 2-kΩ resistor. Avoid direct connection to long cables or unbuffered ADC inputs exceeding 100 pF.
What is the input bias current specification for TLV2375IDR?
The input bias current for TLV2375IDR is 1 pA typical at 25°C and 1000 pA maximum at +125°C, as specified in Section 7.9 of the datasheet. This ultra-low value results from its CMOS input stage and enables precision amplification of high-impedance sources (e.g., pH electrodes, photodiodes, piezoelectric sensors) without significant voltage error. At room temperature, 1 pA flowing through a 1-GΩ source adds only 1 mV offset - far below the 4.5-mV typical input offset voltage.
