Product details
Overview
TLV2465CPWRG4 from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2465CPWRG4 datasheet, TLV2465CPWRG4 pinout, TLV2465CPWRG4 application, or TLV2465CPWRG4 equivalent, this device is selected for precision analog signal conditioning where rail-to-rail swing, micropower shutdown (0.3 µA/channel), and operation from 2.7 V to 6 V single supply are critical design requirements.
Technical Context
The TLV2465CPWRG4 integrates four independent amplifiers in one TSSOP-16 package, each featuring rail-to-rail input and output stages that extend common-mode range beyond supply rails and deliver full-swing output into heavy loads. Its architecture supports stable unity-gain operation with 160 pF capacitive load and provides 45° phase margin at 5 V supply.
Each channel includes an active-low shutdown terminal (1/2SHDN and 3/4SHDN pins) that places the amplifier in ultralow-current mode while forcing output to high-impedance state - essential for power-gated multi-channel signal chains in battery-powered instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~1 MHz with moderate gain in sensor amplification stages. |
| Slew Rate | 1.6 V/µs - supports 10-bit+ ADC sampling of signals up to ~100 kHz without distortion. |
| Supply Current per Channel | 500 µA - allows four-channel operation under 2 mA total, suitable for always-on monitoring circuits. |
| Input Offset Voltage | 100 µV (typ) - ensures <0.01% gain error in 10 V full-scale precision gain stages. |
| Rail-to-Rail I/O | Input extends beyond rails; output swings within 100 mV of VDD/GND - maximizes dynamic range in 3.3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces quiescent power by >99.9% during idle periods in portable data loggers. |
| Output Drive | ±80 mA - drives 50 Ω cables or multiple parallel inputs without external buffers. |
Pinout & Package
TSSOP-16 (PW) package: 5 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | 1OUT / 4OUT | Amplifier 1 and 4 output terminals - rail-to-rail capable, ±80 mA sink/source. |
| 2, 15 | 1IN− / 4IN− | Inverting inputs - high-impedance (10⁹ Ω), support rail-to-rail common-mode range. |
| 3, 14 | 1IN+ / 4IN+ | Non-inverting inputs - identical CMVR and bias current specs as inverting inputs. |
| 4, 13 | VDD+ | Positive supply rail - accepts 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply. |
| 5, 12 | 2IN+ / 3IN+ | Non-inverting inputs for channels 2 and 3 - electrically isolated, no crosstalk. |
| 6, 11 | 2IN− / 3IN− | Inverting inputs for channels 2 and 3 - matched offset and noise performance. |
| 7, 10 | 2OUT / 3OUT | Amplifier 2 and 3 outputs - independently controllable, same drive capability as pins 1/16. |
| 8 | GND | Analog ground reference - must be low-impedance return path for all channels. |
| 9 | 1/2SHDN | Active-low shutdown control for channels 1 and 2 - pulls output to Hi-Z when <0.7 V. |
| 12 | 3/4SHDN | Active-low shutdown control for channels 3 and 4 - independent of 1/2SHDN pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3 V supply in ADC driver applications - no headroom loss at input or output stage. |
| Micropower shutdown mode | Reduces per-channel current to 0.3 µA, allowing selective channel disabling in multi-sensor systems without PCB redesign. |

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 |
|---|---|---|---|
| TLV2465IPWR | Same electrical specs but rated for −40°C to 125°C industrial temp range (I-suffix); no automotive qualification. | Preferred for industrial PLC analog I/O modules where AEC-Q100 compliance is not required. | Select TLV2465IPWR when extended temperature range suffices and automotive qualification adds unnecessary cost. |
| OPA2333PWR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2465CPWRG4's 2 µV/°C; higher 350 µA/channel supply current. | Better for DC-critical applications like precision weigh scales; less suitable for battery-constrained portable devices. | Choose OPA2333PWR only when sub-µV offset stability over temperature outweighs 70% higher quiescent current. |
Compared with TLV2465IPWR, the TLV2465CPWRG4 offers AEC-Q100 qualification for automotive use but shares identical pinout and electrical behavior; versus OPA2333PWR, it trades zero-drift precision for 3× lower supply current and proven robustness in noisy automotive environments.

FAQ
What is the operating temperature range for TLV2465CPWRG4?
The TLV2465CPWRG4 is qualified for operation from −40°C to 125°C and meets AEC-Q100 Grade 1 automotive reliability standards. This range is explicitly specified in the "Recommended Operating Conditions" table of the SLOS220J datasheet and validated across all electrical parameters including input offset voltage, supply current, and output drive capability.
Does TLV2465CPWRG4 support true rail-to-rail input and output?
Yes, TLV2465CPWRG4 supports rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 100 mV of VDD and GND at ±80 mA load). This is confirmed in the device description, absolute maximum ratings, and electrical characteristics tables - enabling full dynamic range utilization in 3.3 V systems.
How does the shutdown function work on TLV2465CPWRG4?
TLV2465CPWRG4 features two independent active-low shutdown pins: pin 9 (1/2SHDN) controls channels 1 and 2; pin 12 (3/4SHDN) controls channels 3 and 4. When pulled below 0.7 V, each pair enters ultralow-current mode (0.3 µA/channel) and forces its outputs into high-impedance state - verified in the "Electrical Characteristics" section under IDD(SHDN).
What is the maximum capacitive load TLV2465CPWRG4 can drive stably?
TLV2465CPWRG4 maintains ≥30° phase margin driving up to 160 pF capacitive load with 10 kΩ resistive load at unity gain, as shown in Figure 36 ("Phase Margin vs Load Capacitance") and confirmed in the "Operating Characteristics" table. Stability degrades above this value unless isolation resistance is added.
Is TLV2465CPWRG4 pin-compatible with other TLV246x variants?
Yes, TLV2465CPWRG4 uses the standard TSSOP-16 (PW) footprint shared across all TLV2464/TLV2465 variants in that package. Pin functions - including dual shutdown controls (pins 9 and 12), GND (pin 8), and VDD+ (pins 4 and 13) - are identical per the "TLV246x PACKAGE PINOUTS" diagram on page 4 of SLOS220J.
