Product details
Overview
TLV2775IDR from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation (2.5 V to 5.5 V), delivering 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, and micropower shutdown mode (<1 µA per channel). It targets precision signal conditioning in automotive sensor interfaces and portable data acquisition systems.
For engineers reviewing the TLV2775IDR datasheet, TLV2775IDR pinout, TLV2775IDR application, or TLV2775IDR equivalent, key selection criteria include its −40°C to 125°C operating range, 1 mA supply current per channel at 5 V, low 17 nV/√Hz input noise, and compatibility with ADC reference driving and telecom line driver circuits.
Technical Context
The TLV2775IDR implements a high-speed CMOS input stage with rail-to-rail output swing, enabling full dynamic range utilization in low-voltage systems. Its architecture supports stable unity-gain operation with 46° phase margin into 600-Ω loads and delivers 0.005% THD+N at 1 kHz under 5-V supply.
It integrates independent shutdown control for each pair of amplifiers (pins 1/2SHDN and 3/4SHDN), allowing selective channel disablement without affecting others. The device is characterized across extended temperature ranges and meets automotive Q-Temp qualification requirements for reliability-critical applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables fast settling for 12-bit ADC front-ends with ≤1 µs 0.01% settling time. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports closed-loop gains up to 10 at 500 kHz while maintaining stability. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.01% gain error in 10-V full-scale instrumentation amplifiers. |
| Supply Current (per channel) | 1 mA typical at 5 V - allows four-channel operation within 4 mA total, suitable for battery-powered sensors. |
| Rail-to-Rail Output | Swings within 100 mV of rails at 2.2 mA load - maximizes signal headroom in 3.3-V or lower systems. |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - preserves SNR in audio and sensor signal chains with bandwidths below 20 kHz. |
| Shutdown Current | <1 µA per channel - reduces system standby power by >99.9% when channels are disabled. |
Pinout & Package
TLV2775IDR is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Thermal resistance θJA is 725 mW at TA ≤ 25°C, derating at 5.8 mW/°C above ambient.
| 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 use. |
| 3, 4 | 1IN+, GND | Channel 1 non-inverting input and ground reference - GND serves as common return for all four channels and shutdown logic. |
| 5, 6 | 1/2SHDN, VDD | Shared shutdown enable for Channels 1 & 2; main positive supply rail - active-low logic disables both amplifiers simultaneously. |
| 7–10 | 2OUT, 2IN−, 2IN+, NC | Channel 2 output/inverting/non-inverting inputs; NC = no internal connection - pin 10 is unused and must be left floating. |
| 11–14 | 3OUT, 3IN−, 3IN+, 3/4SHDN | Channel 3 output/inverting/non-inverting inputs; shared shutdown for Channels 3 & 4 - independent of pins 5/6. |
| 15, 16 | 4OUT, 4IN− | Channel 4 output and inverting input - completes quad configuration; 4IN+ connects internally to pin 13 (3IN+). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 0–VDD dynamic range into 2.2 mA loads, eliminating level-shifting circuitry in 3.3-V ADC interfaces. |
| Micropower shutdown mode | Reduces per-channel quiescent current to <1 µA, enabling rapid power gating in duty-cycled sensor nodes. |
| Low THD+N (0.005%) | Meets telecom-grade line driver requirements for voice-band signals without post-filtering compensation. |
| Extended temperature range | Specified from −40°C to +125°C, supporting under-hood automotive applications without derating. |
| High CMRR (84 dB min) | Rejects common-mode noise in noisy industrial environments, preserving accuracy in differential sensor readouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2774IDR | No shutdown function; identical pinout except missing SHDN pins (5, 6, 13, 14); same AC/DC specs. | Preferred where continuous operation is required and power gating is unnecessary. | Select TLV2774IDR only if system-level power sequencing eliminates need for per-channel shutdown control. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2775IDR's 2 µV/°C; higher 350 nA input bias current. | Better for long-term DC stability in precision weigh scales; less suitable for high-frequency telecom drivers. | Choose OPA2333AIDR when microvolt-level offset stability over temperature dominates over speed and power. |
Compared with TLV2775IDR, TLV2774IDR removes shutdown capability but simplifies layout and reduces cost, while OPA2333AIDR trades bandwidth and power efficiency for near-zero drift-making TLV2775IDR optimal for mixed-signal systems needing speed, low power, and automotive temperature resilience.

FAQ
What is the operating temperature range for TLV2775IDR?
The TLV2775IDR is rated for operation from −40°C to +125°C, meeting automotive Q-Temp specifications. This range is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current, making it suitable for under-hood and industrial control applications where thermal extremes are present. The I-suffix designation confirms this extended grade.
Does TLV2775IDR support true rail-to-rail input?
No, TLV2775IDR features rail-to-rail *output* only. Its input common-mode voltage range extends from GND to VDD − 1.3 V (at 5 V supply), meaning the non-inverting input cannot accept signals within 1.3 V of VDD. This limitation is documented in the "Recommended Operating Conditions" table and must be considered when designing single-supply sensor interfaces with high-side biasing.
How does the shutdown functionality work on TLV2775IDR?
TLV2775IDR provides two independent shutdown controls: pins 5/6 (1/2SHDN) disable Channels 1 and 2, while pins 13/14 (3/4SHDN) disable Channels 3 and 4. Each is active-low; pulling either pair to GND reduces the respective channel's supply current to <1 µA. Both pairs must be high to enable all four amplifiers. No external pull-up resistors are required-the internal logic handles default-enable behavior.
Can TLV2775IDR drive a 600-Ω load with low distortion?
Yes, TLV2775IDR is specifically characterized for 600-Ω loading: at 1 kHz and AV = 1, it achieves 0.005% THD+N, and at AV = 10, THD+N remains at 0.016%. This performance is verified at both 2.7 V and 5 V supplies and supports telecom line driver applications compliant with ITU-T G.711. The 10.5 V/µs slew rate prevents slewing-induced distortion during large-signal transients.
What is the maximum supply voltage for TLV2775IDR?
The absolute maximum supply voltage for TLV2775IDR is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks exceeding safe power dissipation limits and may degrade long-term reliability-even if within absolute ratings. All AC and DC specifications, including slew rate and bandwidth, are guaranteed only within the 2.5–5.5 V range per the datasheet's "Recommended Operating Conditions" table.
