Product details
Overview
TLV2375IN from Texas Instruments is a quad-channel rail-to-rail input/output operational amplifier with integrated shutdown control for channels 1–2 (1/2SHDN) and 3–4 (3/4SHDN), 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 - used in battery-powered sensor signal conditioning and industrial analog front-ends.
For engineers reviewing the TLV2375IN datasheet, TLV2375IN pinout, TLV2375IN application, or TLV2375IN equivalent, key selection considerations include its 16-pin SOIC/TSSOP/PDIP package, dual-pair shutdown architecture, rail-to-rail I/O performance across −40°C to +125°C, and low 1 pA input bias current enabling high-impedance transducer interfacing.
Technical Context
The TLV2375IN implements CMOS input stage architecture supporting rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing (within 150 mV of rails at 1 mA load), with independent dual shutdown controls enabling selective channel power gating. Its 3-MHz unity-gain bandwidth and 2.4 V/µs slew rate are maintained across 2.7–16 V supply operation.
Shutdown functionality is implemented via active-low logic inputs (1/2SHDN on Pin 8, 3/4SHDN on Pin 9), reducing supply current per channel to 25 µA (typ) at 2.7–5 V and 45 µA (typ) at 15 V. Input offset voltage is specified at 4.5 mV (typ) at 25°C and 6 mV (max) over full temperature range.
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 without level-shifting. |
| Bandwidth (UGBW) | 3 MHz - enables stable closed-loop gain up to ~10× at 300 kHz for anti-aliasing or active filter stages. |
| Slew Rate | 2.4 V/µs - supports 1-Vpp signals up to ~380 kHz full-power bandwidth with <1% distortion. |
| Input Bias Current | 1 pA (max) - permits use with >100 MΩ source impedances (e.g., pH electrodes, piezoelectric sensors) without significant error. |
| Shutdown Current | 25 µA/channel (typ @ 5 V) - reduces total quiescent draw to <100 µA when all four channels disabled. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, motor control feedback, and automotive under-hood sensing. |
| Input Noise Voltage | 39 nV/√Hz @ 1 kHz - suitable for precision DC-coupled amplification where noise floor must remain below 1 µV RMS in 10 kHz BW. |
Pinout & Package
TLV2375IN is available in 16-pin SOIC (D), PDIP (N), and TSSOP (PW) packages. All variants share identical pin numbering and function mapping per TI SLOS270F datasheet Section 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier channel 1 output - drives loads up to ±16 mA; rail-to-rail swing enables full dynamic range utilization. |
| 2 | 1IN− | Inverting input, channel 1 - high-impedance CMOS node; requires matched trace routing for optimal CMRR. |
| 3 | 1IN+ | Noninverting input, channel 1 - accepts common-mode voltages from GND to VDD; no external clamping needed. |
| 4 | VDD | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability. |
| 5 | 2IN+ | Noninverting input, channel 2 - electrically isolated from channel 1; supports independent signal paths. |
| 6 | 2IN− | Inverting input, channel 2 - shares same input stage topology and bias current as Pin 2. |
| 7 | 2OUT | Amplifier channel 2 output - identical drive capability and rail-to-rail behavior as Pin 1. |
| 8 | 1/2SHDN | Active-low shutdown for channels 1 & 2 - pulled high via 100 kΩ resistor to enable; floats to disable. |
| 9 | 3/4SHDN | Active-low shutdown for channels 3 & 4 - independent control allows staggered wake-up sequencing. |
| 10 | 3OUT | Amplifier channel 3 output - fully functional with same AC/DC specs as Pins 1 and 7. |
| 11 | 3IN− | Inverting input, channel 3 - matches input capacitance (8 pF) and bias current of other inputs. |
| 12 | 3IN+ | Noninverting input, channel 3 - supports same common-mode range and noise rejection as Pin 3. |
| 13 | GND | Analog ground reference - must connect to low-impedance PCB plane; separate from digital ground if mixed-signal layout. |
| 14 | 4IN+ | Noninverting input, channel 4 - enables simultaneous 4-channel signal acquisition without multiplexing. |
| 15 | 4IN− | Inverting input, channel 4 - maintains 1 pA bias current and 39 nV/√Hz noise density. |
| 16 | 4OUT | Amplifier channel 4 output - completes quad configuration; supports independent gain-setting resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464CDR | Higher supply current (550 µA vs 550 µA), lower GBW (6.4 MHz), no shutdown, rail-to-rail output only. | Lacks shutdown control and rail-to-rail input - unsuitable for high-impedance sensor interfaces requiring full common-mode range. | Select TLV2464CDR only when higher bandwidth is prioritized over power gating and input range. |
| OPA4340UA | Lower input bias current (0.2 pA), higher cost, no shutdown, rail-to-rail output only, 5.5 V max supply. | Cannot operate from 12 V or 16 V rails; lacks shutdown for energy-constrained wireless nodes. | Choose OPA4340UA only for ultra-low-bias applications below 5.5 V where shutdown is unnecessary. |
Compared with TLV2464CDR and OPA4340UA, the TLV2375IN uniquely combines rail-to-rail input/output, dual-pair shutdown, 16 V operation, and 1 pA bias in a single quad package - making it the only option among the three that supports both wide-supply industrial systems and ultra-low-power portable designs.

FAQ
What is the maximum supply voltage for TLV2375IN?
The absolute maximum supply voltage for TLV2375IN is 16.5 V, but the recommended operating range is 2.7 V to 16 V per the TI SLOS270F datasheet. Operation above 16 V risks permanent damage, while operation below 2.7 V may cause degraded rail-to-rail output swing and increased input offset voltage. The TLV2375IN is rated for continuous operation at 16 V, supporting applications powered from 12 V industrial rails or ±8 V split supplies.
Does TLV2375IN support true rail-to-rail input?
Yes, TLV2375IN supports true rail-to-rail input: its common-mode input voltage range extends from GND (0 V) to VDD, verified across the full −40°C to +125°C temperature range. This allows direct connection of sensors referenced to either supply rail without external level-shifting circuitry. The input stage uses complementary CMOS topology, enabling this full-range operation while maintaining 1 pA typical input bias current.
How does the dual-pair shutdown function work on TLV2375IN?
TLV2375IN features two independent active-low shutdown pins: Pin 8 (1/2SHDN) disables channels 1 and 2, while Pin 9 (3/4SHDN) disables channels 3 and 4. When pulled low (<0.8 V), each pair enters shutdown mode drawing only 25 µA/channel (typ). Both pins can be left floating (internal pull-up ensures operation) or tied together for global shutdown. This architecture enables selective power gating - for example, keeping channels 1–2 active for continuous monitoring while shutting down 3–4 during data transmission pauses.
What is the typical input offset voltage of TLV2375IN?
The typical input offset voltage of TLV2375IN is 4.5 mV at 25°C, with a maximum of 6 mV across the full −40°C to +125°C operating range. This specification is measured with VDD = 2.7–15 V, common-mode input at VDD/2, and output at VDD/2. The offset drift is 2 µV/°C (typ), contributing <0.25 mV additional error over a 125°C span. For precision applications, external trimming or auto-zero architectures may be required beyond this inherent offset.
Which packages are available for TLV2375IN?
TLV2375IN is offered in three industry-standard packages: 16-pin SOIC (D), 16-pin PDIP (N), and 16-pin TSSOP (PW). All share identical pinout and electrical specifications per TI's SLOS270F datasheet. The SOIC variant measures 9.9 mm × 3.91 mm, PDIP is 19.3 mm × 6.35 mm, and TSSOP is 5.0 mm × 4.4 mm - allowing selection based on board space, thermal requirements (RθJA = 83°C/W for SOIC, 55.8°C/W for PDIP), and assembly capability.
