Product details
Overview
TLV2775CPW from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply portable and precision analog signal conditioning. It delivers 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, 360 µV input offset voltage (typ), 17 nV/√Hz input noise, and micropower shutdown (<1 µA per channel) in a 16-pin TSSOP package. It drives ADC reference inputs and telecom 600-Ω loads with 0.005% THD+N at 5 V.
For engineers reviewing the TLV2775CPW datasheet, TLV2775CPW pinout, TLV2775CPW application, or TLV2775CPW equivalent, this page provides verified electrical specs, thermal-rated package details, real-world use cases in automotive sensor interfaces and medical front-ends, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2775CPW integrates four independent high-speed amplifiers sharing a common 2.5–5.5 V supply. Each channel features a CMOS input stage with 2 pA bias current and rail-to-rail output swing capable of sourcing/sinking ±2.2 mA at 5 V. Its internal architecture supports stable unity-gain operation with 46° phase margin into 600-Ω + 100-pF loads.
It includes individual shutdown control for channels 1/2 and 3/4 (pins 6 and 13), enabling dynamic power management. The device is characterized across −40°C to 125°C (I-suffix), with guaranteed performance at 2.7 V and 5 V, making it suitable for automotive body electronics and industrial data acquisition where supply headroom is constrained.
Key Specifications

|---|---|
| Gain-bandwidth product | 5.1 MHz - enables stable closed-loop gain up to ~50 at 100 kHz for anti-aliasing filter design |
| Slew rate | 10.5 V/µs - supports clean 1-Vpp signals up to ~1.5 MHz without distortion |
| Input offset voltage | 360 µV (typ) - ensures <0.1% error in 0.36-V full-scale sensor signal conditioning |
| Supply current per channel | 1 mA (typ) - allows four-channel operation within 4.5-mA total budget for battery-powered systems |
| Shutdown current | 0.8–1.5 µA (typ) - reduces quiescent draw by >99.9% when unused channels are disabled |

Pinout & Package
TSSOP-16 (PW) package: 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant, rated for 125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - rail-to-rail swing, ±2.2 mA drive capability into 600 Ω |
| 2 | 1IN− | Inverting input - high-impedance CMOS node (10¹² Ω), low 2-pA bias current |
| 3 | 1IN+ | Non-inverting input - matched to pin 2 for optimal common-mode rejection |
| 4 | GND | Analog ground reference - must be low-impedance plane for noise-sensitive applications |
| 5 | NC | No internal connection - leave unconnected; no routing or thermal relief required |
| 6 | 1/2SHDN | Active-low shutdown enable for channels 1 and 2 - pulls IDD to <1.5 µA when high |
| 7 | VDD | Positive supply - accepts 2.5–5.5 V; bypass with 0.1-µF ceramic capacitor near pin |
| 8 | 2OUT | Channel 2 output - identical AC/DC specs to pin 1, independent output stage |
| 9 | 2IN− | Inverting input for channel 2 - electrically isolated from other channels |
| 10 | 2IN+ | Non-inverting input for channel 2 - matched pair with pin 9 |
| 11 | NC | No internal connection - floating; no effect on operation if tied to GND or VDD |
| 12 | 3OUT | Channel 3 output - fully independent; shares VDD/GND but no crosstalk above −80 dB |
| 13 | 3/4SHDN | Active-low shutdown for channels 3 and 4 - separate control from pin 6 |
| 14 | 3IN− | Inverting input for channel 3 - same layout symmetry as pins 2 and 9 |
| 15 | 3IN+ | Non-inverting input for channel 3 - matched pair with pin 14 |
| 16 | 4OUT | Channel 4 output - final channel; pin 16 is standard output location in TSSOP-16 op-amp layout |

|---|---|
Use Scenario: Signal conditioning for piezoresistive pressure sensors in HVAC control modules, operating at 125°C ambient. IC Role / Device Role / Timing Role: Quad op-amp configures as instrumentation amp (ch1–ch2), reference buffer (ch3), and ADC driver (ch4) - all powered from 3.3-V MCU rail. Use Value: Rail-to-rail output ensures full 0–3.3-V ADC utilization; 360-µV offset contributes <0.01% FS error at 300-kPa full scale. | Use Scenario: Low-noise, low-power amplification of 0.5–2-mV biopotential signals in handheld ECG monitors. IC Role / Device Role / Timing Role: Ch1–ch2 form differential input stage; ch3 buffers reference voltage; ch4 drives SAR ADC input with 0.005% THD+N. Use Value: 17-nV/√Hz noise floor preserves diagnostic fidelity; 1-mA/channel current enables >24-hour battery life on coin cell. |
| Industrial 4–20-mA Loop Transmitter | Telecom Line Driver for VoIP Analog FXS Port |
Use Scenario: Voltage-to-current conversion and loop-powered sensor interface in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Ch1 amplifies sensor voltage; ch2 implements Howland current source; ch3–ch4 provide isolation feedback and diagnostics. Use Value: Micropower shutdown (pin 6/13) cuts standby current to <2 µA during sleep mode - critical for energy harvesting nodes. | Use Scenario: Driving POTS line impedance (600 Ω) from VoIP gateway FXS port while meeting FCC Part 68 harmonic limits. IC Role / Device Role / Timing Role: Single TLV2775CPW replaces dual op-amps: one channel for transmit path amplification, another for hybrid echo cancellation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464CDR | Lower slew rate (1.6 V/µs), higher supply current (550 µA/ch), I/O rail-to-rail, 6.4-MHz GBW | Better DC precision (250-µV VIO max) but insufficient speed for >100-kHz signal paths | Select when ultra-low offset and lower power dominate over bandwidth - e.g., precision weight scales |
| OPA4340UA | Higher precision (125-µV VIO max), lower noise (11 nV/√Hz), 5.5-MHz GBW, 5.5-V max supply | Requires ≥2.7-V supply; not rated for 125°C operation; no shutdown function | Choose for medical-grade analog front-ends where noise and offset are critical, and temperature range ≤105°C |
Compared with TLV2775CPW, TLV2464CDR trades bandwidth and shutdown for lower offset and cost, while OPA4340UA improves noise and offset at the expense of thermal rating and power management - making TLV2775CPW the only option supporting automotive-grade operation with integrated power gating.

FAQ
What is the maximum operating junction temperature for TLV2775CPW?
The TLV2775CPW is rated for operation up to 150°C junction temperature. Its I-suffix qualification guarantees full electrical performance from −40°C to +125°C ambient, and the TSSOP-16 package's thermal resistance (θJA = 120°C/W) allows safe operation at 125°C ambient with ≤300 mW dissipation - sufficient for four active channels at 5 V and 1 mA each.
Does TLV2775CPW support true rail-to-rail input?
No, TLV2775CPW features rail-to-rail *output* only. Its input common-mode range extends from GND to VDD − 1.3 V (at 2.7 V supply) or VDD − 1.3 V (at 5 V supply), as specified in the recommended operating conditions table. For true rail-to-rail input, consider TI's TLV2474 or OPA4340 - but neither offers the same combination of 10.5 V/µs slew rate and shutdown capability.
Can TLV2775CPW drive a 100-pF capacitive load stably?
Yes, TLV2775CPW is characterized for stability with 100-pF capacitive loads in unity-gain configuration, delivering 46° phase margin and 12 dB gain margin when driving 600 Ω in parallel (per operating characteristics, VDD = 5 V). For loads >100 pF or purely capacitive loads, a series resistor (≥10 Ω) between output and capacitance is recommended to maintain stability.
What is the turn-on time for TLV2775CPW's shutdown feature?
The TLV2775CPW exhibits 1.9 µs amplifier turn-on time (tON) from shutdown to 50% output level, measured at AV = 5 with open-load condition (datasheet SLOS209G, page 9). This enables rapid channel activation in burst-mode sensor readouts without compromising system power savings.
Is TLV2775CPW pin-compatible with other TLV277x variants in TSSOP-16?
Yes, all TLV277x devices in the PW (TSSOP-16) package - including TLV2774CPW and TLV2775CPW - share identical pinouts and footprint. The only functional difference is that TLV2775CPW includes dual shutdown control (pins 6 and 13), whereas TLV2774CPW has a single 1/2/3/4SHDN pin (pin 6) - requiring minor schematic updates if substituting between them.
