Product details
Overview
TLV2635ID from Texas Instruments is a quad-channel, rail-to-rail output operational amplifier with shutdown capability, designed for precision signal conditioning in space-constrained industrial systems. It operates from 2.7 V to 5.5 V, delivers 9 MHz gain-bandwidth at 730 µA/channel, supports −40°C to 125°C operation, and features ground-sensing input (VICR = GND to VDD−1 V) - enabling direct interface with ground-referenced sensors and data converters.
For engineers reviewing the TLV2635ID datasheet, TLV2635ID pinout, TLV2635ID application, or TLV2635ID equivalent, this page provides verified electrical parameters, SOIC-16 package layout, real-world use cases in high-resolution ADC driver and battery-powered sensor front-ends, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2635ID integrates four independent amplifiers in a single SOIC-16 package, each with individual shutdown control (pins 1/2SHDN and 3/4SHDN), rail-to-rail output swing, and input common-mode range extending to ground. Its 9 MHz GBW and 9.5 V/µs negative slew rate support stable unity-gain buffer and gain-of-10 configurations driving capacitive loads up to 10 pF.
It employs a CMOS input stage delivering ultra-low input bias current (1–50 pA typ), low input offset voltage (250–5200 µV over temperature), and 50 nV/√Hz input voltage noise - making it suitable for high-impedance source amplification and low-distortion signal chains where THD+N remains ≤0.095% at 10 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 9 MHz - enables stable closed-loop operation up to ~1 MHz at gain ≥10 without phase margin degradation. |
| Supply Current per Channel | 730 µA - allows four-channel operation under 3 mA total, ideal for microcontroller-based portable instrumentation. |
| Rail-to-Rail Output Swing | VOL = 0.025–0.47 V, VOH = 4.7–4.98 V (at VDD = 5 V, IO = ±10 mA) - maximizes dynamic range when interfacing with 5 V ADCs or DACs. |
| Input Common-Mode Range | GND to VDD−1 V - permits direct connection to ground-referenced transducers and single-supply sensor outputs. |
| Shutdown Supply Current | 4–19 µA per channel - reduces system standby power by >99% versus active mode, critical for battery longevity. |
| Operating Temperature Range | −40°C to 125°C - qualified for under-hood automotive, industrial PLC I/O modules, and motor drive feedback circuits. |
| Total Harmonic Distortion + Noise | 0.095% at AV = 100, f = 10 kHz - preserves fidelity in audio-grade and high-speed data acquisition paths. |
Pinout & Package
TLV2635ID is supplied in a 16-pin SOIC (D) package, 10.3 mm × 7.5 mm footprint, 2.35 mm height, RoHS-compliant NIPDAU lead finish, MSL Level-1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | 1OUT, 1IN− | Channel 1 output and inverting input - configured as standard op-amp node; requires external feedback for closed-loop operation. |
| 3, 4 | 1IN+, GND | Channel 1 non-inverting input and device ground reference - GND pin must be low-impedance connection to system return plane. |
| 5, 6 | VDD, 2OUT | Positive supply rail and Channel 2 output - VDD supplies all four channels; decoupling capacitor required within 1 cm of pin 5. |
| 7, 8 | 2IN−, 2IN+ | Channel 2 inverting and non-inverting inputs - identical electrical behavior to Channel 1; supports differential input configuration. |
| 9, 10 | 1/2SHDN, 4OUT | Shared shutdown control for Channels 1 & 2, and Channel 4 output - logic-low on pin 9 disables Channels 1 and 2 simultaneously. |
| 11, 12 | 4IN−, 4IN+ | Channel 4 inverting and non-inverting inputs - electrically isolated from other channels; usable as independent signal path. |
| 13, 14 | GND, 3OUT | Second ground pin and Channel 3 output - dual GND pins reduce ground bounce in multi-channel switching applications. |
| 15, 16 | 3IN+, 3/4SHDN | Channel 3 non-inverting input and shared shutdown for Channels 3 & 4 - pin 16 logic-low disables Channels 3 and 4 only. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale analog output across entire 2.7–5.5 V supply range, eliminating level-shifting circuitry in mixed-voltage systems. |
| Ground-sensing input (VICR = GND to VDD−1 V) | Directly interfaces with 0 V–referenced thermocouples, bridge sensors, and current-sense resistors without input biasing networks. |
| Independent dual shutdown groups | Pins 9 and 16 enable selective power gating of Channel pairs (1+2 or 3+4), supporting dynamic channel activation in multi-sensor arrays. |
| Low 50 nV/√Hz input voltage noise | Preserves SNR in high-gain, low-level signal amplification stages - critical for 16-bit+ SAR and sigma-delta ADC front-ends. |
| −40°C to 125°C extended temperature grade | Validated performance across full industrial temperature range, ensuring reliability in uncontrolled environments like factory floors or outdoor enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2784IDR | Lower supply voltage (1.8–3.6 V), 8 MHz GBW, 650 µA/channel, no shutdown function. | Limited to low-voltage systems; unsuitable for 5 V ADC interfaces or shutdown-controlled power sequencing. | Select when operating exclusively below 3.6 V and shutdown is unnecessary; avoid if rail-to-rail output at 5 V or channel gating is required. |
| OPA4343UA | Higher supply current (8.5 mA/channel), 44 MHz GBW, 22 V/µs slew rate, no shutdown, wider VDD range (2.7–5.5 V). | Excess bandwidth and speed increase power consumption 11×; not optimized for battery or thermally constrained designs. | Choose only when >10 MHz closed-loop bandwidth or >10 V/µs slew is mandatory; TLV2635ID is superior for low-power, precision, and integrated shutdown needs. |
Compared with TLV2784IDR and OPA4343UA, the TLV2635ID uniquely balances 9 MHz bandwidth, 730 µA/channel efficiency, rail-to-rail output at 5 V, ground-sensing input, and dual-group shutdown - making it the optimal choice for industrial data loggers, multi-sensor nodes, and energy-conscious analog front-ends requiring guaranteed −40°C to 125°C operation.

FAQ
What is the maximum recommended supply voltage for TLV2635ID?
The absolute maximum supply voltage for TLV2635ID is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operating above 5.5 V risks permanent damage and violates TI's specified conditions. At 5.5 V, the device maintains full rail-to-rail output swing and meets all AC/DC specifications across −40°C to 125°C.
Does TLV2635ID support true rail-to-rail input operation?
No, TLV2635ID does not support rail-to-rail input. Its input common-mode voltage range is specified as GND to VDD−1 V. This means the input can reach ground but cannot swing to the positive rail - a deliberate design trade-off to achieve low input bias current and high CMRR while maintaining stability at low supply voltages.
How many independent shutdown controls does TLV2635ID provide?
TLV2635ID provides two independent shutdown controls: pin 9 (1/2SHDN) disables Channels 1 and 2, and pin 16 (3/4SHDN) disables Channels 3 and 4. Each control requires a logic-low signal ≤0.4 V to activate shutdown, drawing only 4–19 µA per channel in that state - enabling granular power management in multi-channel systems.
What is the typical input offset voltage of TLV2635ID at room temperature?
The typical input offset voltage of TLV2635ID at 25°C is 250 µV for Channels 1–2 and 4200 µV for Channels 3–4 (per datasheet Table 1). The higher value for Channels 3–4 reflects process variation across the quad die; designers should verify offset-critical applications using the max full-range spec of 5200 µV.
Can TLV2635ID drive a 10 kΩ load while maintaining rail-to-rail output?
Yes, TLV2635ID can drive a 10 kΩ load with rail-to-rail output swing. At VDD = 5 V and IO = ±1 mA, VOH = 4.92–4.98 V and VOL = 0.025–0.08 V - confirming full swing within 80 mV of rails. For heavier loads (e.g., 2 kΩ), output swing degrades slightly but remains >95% of rail-to-rail range per datasheet Figures 4–7.
