Product details
Overview
TLV2464CDR 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, 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 TLV2464CDR datasheet, TLV2464CDR pinout, TLV2464CDR application, or TLV2464CDR equivalent, this page provides verified package mapping (TSSOP-14), confirmed shutdown functionality per channel, rail-to-rail dynamic range at 2.7–6 V supply, and real-world design guidance for industrial sensor conditioning and automotive body electronics.
Technical Context
The TLV2464CDR implements a CMOS input stage with rail-to-rail input common-mode range extending beyond supply rails and rail-to-rail output swing delivering full dynamic range in single-supply 2.7–6 V systems. Its 6.4 MHz GBW and 1.6 V/µs slew rate support medium-speed signal conditioning without compromising micropower operation.
Each of the four amplifiers features independent shutdown control (pins 1/2SHDN and 3/4SHDN), reducing per-channel supply current to 0.3 µA in shutdown while placing the output in high-impedance state - critical for power-gated multi-channel analog subsystems in battery-powered equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer configurations up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - enables clean 10-bit+ signal reproduction for 100 kHz full-scale sine waves at 3 V supply. |
| Supply Current / Channel | 500 µA - allows four-channel operation at <2 mA total, suitable for always-on sensor nodes. |
| Input Offset Voltage | 100 µV - ensures ≤0.002% gain error in precision 12-bit sensor signal chains at room temperature. |
| Rail-to-Rail I/O | Full swing from VDD to GND - eliminates level-shifting components when interfacing with 3.3 V ADCs or microcontrollers. |
| Output Drive | ±80 mA - drives 37.5 Ω loads directly, supporting active filters and low-impedance transducer interfaces. |
| Shutdown Current / Channel | 0.3 µA - reduces quiescent power by >99.9% per disabled amplifier in multi-stage signal paths. |
Pinout & Package
TSSOP-14 package (PW suffix), 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, moisture sensitivity level 1 (MSL-1), tape-and-reel packaging (R suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - connects directly to ADC input or filter stage; rail-to-rail swing supports full-scale utilization. |
| 2 | 1IN− | Inverting input for Amp A - accepts differential or single-ended feedback networks; high-impedance CMOS input minimizes loading. |
| 3 | 1IN+ | Non-inverting input for Amp A - used for unity-gain buffer or sensor reference biasing; rail-to-rail common-mode range includes GND and VDD. |
| 4 | GND | Analog ground reference - must be low-impedance star point shared with ADC and reference; separate from digital ground. |
| 5 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 6 | 1/2SHDN | Shared shutdown control for Amps A and B - logic-high (>2 V) enables both; logic-low (<0.7 V) disables both with 0.3 µA/ch quiescent draw. |
| 7 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 8 | VDD+ | Positive supply rail - accepts 2.7–6 V single supply; decoupling capacitor (100 nF) required within 5 mm of pin. |
| 9 | 4OUT | Amplifier D output - identical performance to Pin 1; enables independent signal paths in multi-sensor systems. |
| 10 | 4IN− | Inverting input for Amp D - electrically isolated from other channels; supports independent gain-setting resistors. |
| 11 | 4IN+ | Non-inverting input for Amp D - usable for reference voltage distribution or dedicated sensor biasing. |
| 12 | GND | Analog ground reference - same net as Pin 4; maintains low-noise return path for all four amplifiers. |
| 13 | 3IN+ | Non-inverting input for Amp C - supports independent configuration; no crosstalk with Pins 1–3 due to physical separation. |
| 14 | 3IN− | Inverting input for Amp C - routed separately from other inputs to preserve channel isolation in mixed-signal PCB layouts. |
| 15 | 3OUT | Amplifier C output - matches Pin 1 electrical specs; enables simultaneous processing of four analog signals without multiplexing delay. |
| 16 | 3/4SHDN | Shared shutdown control for Amps C and D - independent of Pin 6, allowing asymmetric power management across the quad array. |
Key Features

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 |
|---|---|---|---|
| TLV2464IDR | Same electrical specs but rated for −40°C to 125°C (I-suffix); 1500 µV max VIO vs 2000 µV for C-suffix. | Required for automotive under-hood or industrial high-temp environments where extended temperature validation is mandatory. | Select TLV2464IDR when operating above 70°C ambient or requiring AEC-Q100 qualification support documentation. |
| OPA4340UA | Higher precision (50 µV VIO), lower noise (8 nV/√Hz), but 750 µA/channel supply current and no shutdown function. | Better suited for high-resolution medical instrumentation where power is secondary to accuracy and noise floor. | Choose OPA4340UA only when 100 µV offset is insufficient and system power budget allows +50% per-channel current increase. |
Compared with TLV2464IDR, the TLV2464CDR trades extended temperature range and tighter offset for lower cost and sufficient performance in commercial-grade portable equipment; versus OPA4340UA, it offers integrated shutdown and 33% lower supply current at the expense of 2× input offset voltage.

FAQ
What is the operating temperature range for TLV2464CDR?
The TLV2464CDR is specified for 0°C to 70°C ambient operation (C-suffix). This range is validated per TI's recommended operating conditions and absolute maximum ratings - making it suitable for commercial and consumer-grade portable equipment but not for under-hood automotive or extended industrial environments. For those applications, the TLV2464IDR (−40°C to 125°C) is the qualified alternative.
Does TLV2464CDR support true rail-to-rail input and output?
Yes, TLV2464CDR supports rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 10 mV of GND and VDD at ±40 mA load). This is confirmed in the datasheet's "Features" section and electrical characteristics tables for VOH/VOL across supply voltages - enabling direct interfacing with 3.3 V ADCs and microcontrollers without level-shifting circuitry.
How does the shutdown feature work on TLV2464CDR?
The TLV2464CDR has two independent shutdown pins: Pin 6 (1/2SHDN) controls amplifiers A and B, and Pin 16 (3/4SHDN) controls amplifiers C and D. Driving either pin below 0.7 V places its pair into ultralow-current mode (0.3 µA/channel), with outputs entering high-impedance state. Both pins must be >2 V to enable all four amplifiers - verified in the "Electrical Characteristics" table under IDD(SHDN).
What is the maximum capacitive load TLV2464CDR can drive stably?
TLV2464CDR maintains stability with up to 160 pF capacitive load when driving a 10 kΩ resistive load, as confirmed by phase margin measurements (44°–45°) in the "Operating Characteristics" table. For loads exceeding 160 pF, external isolation resistance (≥100 Ω) is required between amplifier output and capacitance to prevent peaking or oscillation - per Figure 36 (Phase Margin vs Load Capacitance).
Is TLV2464CDR pin-compatible with other packages in the TLV246x family?
No - TLV2464CDR uses the TSSOP-14 (PW) package, which has a unique 14-pin layout with dual shutdown controls and NC pins. It is not pin-compatible with the SOIC-14 (D), PDIP-14 (N), or ceramic packages. Pin compatibility exists only within the same package type (e.g., TLV2464CDR and TLV2464IDR share identical TSSOP-14 pinout and footprint).
