Product details
Overview
TLV2464AIDR from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-power portable and automotive 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 operating from 2.7 V to 6 V.
For engineers reviewing the TLV2464AIDR datasheet, TLV2464AIDR pinout, TLV2464AIDR application, or TLV2464AIDR equivalent, this device is selected for precision analog signal conditioning where rail-to-rail swing, low quiescent current, shutdown capability, and extended temperature operation (−40°C to 125°C) are required in space-constrained TSSOP-14 layouts.
Technical Context
The TLV2464AIDR integrates four independent amplifiers with complementary-input-stage architecture enabling true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing. Each channel supports micropower shutdown (0.3 µA/channel), placing its output in high-impedance state while retaining fast turnon/turnoff times (7.65 µs / 328 ns).
It operates across 2.7 V–6 V single-supply or ±1.35 V–±3 V split-supply configurations, with guaranteed performance over −40°C to 125°C. Input noise voltage is 11 nV/√Hz at 1 kHz, CMRR is 85 dB (typ), and supply voltage rejection ratio reaches 95 dB (typ) - supporting stable DC accuracy and AC fidelity in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain buffer or closed-loop gain ≥10 up to ~600 kHz without phase margin degradation. |
| Slew Rate | 1.6 V/µs - supports clean 1 VPP signals up to ~250 kHz in unity-gain follower configuration. |
| Supply Current per Channel | 500 µA - allows four-channel operation at <2 mA total, ideal for battery-powered instrumentation. |
| Input Offset Voltage | 100 µV (max at 25°C) - ensures ≤0.002% gain error in 5 V full-scale precision sensor amplification. |
| Output Drive Capability | ±80 mA - drives 62 Ω loads to rails, sufficient for driving SAR ADC reference buffers or active filters. |
| Rail-to-Rail I/O | Input common-mode range 0 V to VDD; output swing within 100 mV of rails at 10 mA - maximizes dynamic range in low-voltage systems. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode, critical for duty-cycled sensing nodes. |
Pinout & Package
TLV2464AIDR is housed in a 14-pin TSSOP (PW) package with exposed thermal pad (not electrically connected). Pin numbering follows standard JEDEC TSSOP layout with pin 1 marked by beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - rail-to-rail capable, ±80 mA sink/source, high-impedance in shutdown. |
| 2 | 1IN− | Inverting input of Amp A - differential input resistance 10⁹ Ω, bias current ≤75 nA (full temp range). |
| 3 | 1IN+ | Non-inverting input of Amp A - supports common-mode voltages from GND to VDD. |
| 4 | GND | Analog ground reference - must be low-impedance connection; ties internal ESD structures and substrate. |
| 5 | NC | No internal connection - left floating; no routing or soldering required. |
| 6 | 1SHDN | Channel A shutdown control - logic-high (>2 V) enables; logic-low (<0.7 V) disables with 0.3 µA quiescent draw. |
| 7 | NC | No internal connection - unused pin; maintain open or grounded per layout best practices. |
| 8 | VDD+ | Positive supply rail - accepts 2.7 V–6 V; decoupling capacitor (0.1 µF) required adjacent to pin. |
| 9 | 2OUT | Amplifier B output - identical electrical specs to Pin 1; shares same VDD+ and GND. |
| 10 | 2IN− | Inverting input of Amp B - electrically isolated from other channels; matched to Pin 2. |
| 11 | 2IN+ | Non-inverting input of Amp B - supports same rail-to-rail common-mode as Pin 3. |
| 12 | NC | No internal connection - not bonded; avoid routing traces to prevent parasitic coupling. |
| 13 | 2SHDN | Channel B shutdown control - independent control from Pin 6; enables selective channel disabling. |
| 14 | NC | No internal connection - mechanical support pin only; no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full 0–VDD signal swing in single-supply systems, preserving SNR in 3.3 V or lower ADC interfaces. |
| Micropower shutdown (0.3 µA/ch) | Reduces total quiescent current to <1.2 µA for all four channels - extends battery life in intermittent-sampling applications. |
| −40°C to 125°C operation | Qualified for automotive underhood and industrial control environments without derating or external heating/cooling. |
| Low input noise (11 nV/√Hz) | Minimizes added noise in precision sensor signal chains (e.g., strain gauges, RTDs) without requiring additional filtering. |
| High output drive (±80 mA) | Eliminates need for external buffer stages when driving capacitive loads (e.g., ADC sample capacitors) or low-Z networks. |
| Independent per-channel shutdown | Allows dynamic power management: e.g., disable unused op-amps in multi-function analog front-ends without affecting others. |

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 | Higher max input offset voltage (2000 µV vs. 1500 µV), same 500 µA/channel supply current and 6.4 MHz GBW. | Approved for industrial (−40°C to 125°C) but not AEC-Q100 qualified; lacks automotive qualification documentation. | Select TLV2464IDR only if AEC-Q100 compliance is unnecessary and cost sensitivity outweighs offset-critical performance. |
| OPA4340UA | Lower input offset (125 µV max), higher supply current (750 µA/ch), no shutdown function, SOIC-14 package only. | Optimized for ultra-low-noise (8 nV/√Hz) precision but lacks power-gating capability and automotive temp range. | Choose OPA4340UA when ultimate DC accuracy and noise dominate over power savings and temperature robustness. |
Compared with TLV2464IDR, TLV2464AIDR provides tighter input offset and automotive qualification; compared with OPA4340UA, it trades 250 µA/channel quiescent current and shutdown for 3 nV/√Hz higher noise and broader temperature reliability - making it optimal for automotive and industrial battery-constrained designs requiring configurable power states.

FAQ
What is the maximum operating temperature range for TLV2464AIDR?
The TLV2464AIDR is specified for continuous operation from −40°C to +125°C ambient temperature. This rating is validated per AEC-Q100 Grade 2 requirements and applies across full electrical specifications including input offset voltage, CMRR, and output drive capability - making it suitable for under-hood automotive and industrial control environments.
Does TLV2464AIDR support true rail-to-rail input and output simultaneously?
Yes, TLV2464AIDR supports rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 100 mV of rails at 10 mA load) in the same operating condition. This dual rail-to-rail capability preserves full dynamic range in single-supply 3.3 V or 5 V systems without external level-shifting circuitry.
How does the shutdown feature work on TLV2464AIDR?
Each amplifier in TLV2464AIDR has an independent shutdown pin (Pins 6 and 13). Driving the pin below 0.7 V places that channel into ultralow-current mode (0.3 µA/channel), disabling output stage and placing the output in high-impedance state. The remaining active channels continue normal operation without interference.
What is the typical input noise voltage of TLV2464AIDR at 1 kHz?
The typical equivalent input noise voltage of TLV2464AIDR is 11 nV/√Hz at 1 kHz, measured with VDD = 3 V or 5 V and TA = 25°C. This value remains stable across the full −40°C to 125°C range and supports low-noise amplification of microvolt-level sensor signals without significant SNR degradation.
Can TLV2464AIDR drive capacitive loads directly?
TLV2464AIDR can safely drive up to 160 pF capacitive loads while maintaining ≥44° phase margin at unity gain, as verified in the datasheet's stability characterization. For larger loads (e.g., ADC input capacitors >200 pF), a small series resistor (10–50 Ω) between amplifier output and load is recommended to ensure stability.
