Product details
Overview
TLV2463AIN from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier with shutdown capability, designed for low-power portable and automotive signal conditioning. 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 buffering of analog-to-digital converters in 2.7–6 V systems.
For engineers reviewing the TLV2463AIN datasheet, TLV2463AIN pinout, TLV2463AIN application, or TLV2463AIN equivalent, this device is selected for precision, low-voltage, rail-to-rail performance in space-constrained industrial sensors, automotive body electronics, and battery-powered data acquisition where micropower shutdown (0.3 µA/channel) and extended temperature operation (−40°C to 125°C) are critical.
Technical Context
The TLV2463AIN implements a CMOS input stage with rail-to-rail common-mode input range extending beyond both supply rails, supporting full dynamic range in single-supply 2.7–6 V applications. Its output stage delivers true rail-to-rail swing with ±80 mA drive capability at 5 V, overcoming limitations of earlier rail-to-rail op-amps.
It integrates an active shutdown terminal that places each amplifier into ultralow-current mode (0.3 µA/channel), while forcing the output into high-impedance state - essential for power-gated sensor front-ends and multiplexed analog signal paths. The device is specified across −40°C to 125°C and qualified per automotive standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - supports stable unity-gain buffer and closed-loop amplification up to ~1 MHz with phase margin >44°. |
| Slew rate | 1.6 V/µs - enables accurate reproduction of 100 kHz full-scale sine waves at 2 VPP without distortion. |
| Input offset voltage | 100 µV (typ) - ensures ≤0.002% gain error in 5 V full-scale instrumentation amplifier configurations. |
| Supply current per channel | 500 µA - allows continuous operation for >1 year on a 200 mAh coin cell in always-on sensor nodes. |
| Shutdown current per channel | 0.3 µA - reduces system standby power by >99.9% versus active mode, critical for duty-cycled measurement systems. |
| Rail-to-rail I/O | Input common-mode range: 0 V to VDD; output swing: within 100 mV of rails - maximizes ADC utilization in single-supply systems. |
| Output drive | ±80 mA - drives 60 Ω loads directly (e.g., coaxial cable termination) without external buffers. |
Pinout & Package
TLV2463AIN is housed in a 14-pin plastic DIP (N) package with through-hole mounting and industry-standard pin spacing. The package supports manual soldering and wave soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-drive rail-to-rail output capable of sourcing/sinking ±80 mA at 5 V. |
| 1IN− | Channel 1 inverting input | CMOS input with 1.3 nA bias current (typ) and rail-to-rail common-mode range. |
| 1IN+ | Channel 1 non-inverting input | Matches 1IN− in offset, noise, and common-mode behavior; used for precision differential sensing. |
| GND | Analog ground reference | Common return for both channels and shutdown logic; must be low-impedance for noise immunity. |
| NC | No internal connection | Pin 5 is unconnected - no routing or grounding required; electrically isolated. |
| 1SHDN | Channel 1 shutdown control | Active-high logic: ≥2 V enables channel; ≤0.7 V disables (0.3 µA/ch, high-Z output). |
| NC | No internal connection | Pin 7 is unconnected - no routing or grounding required; electrically isolated. |
| VDD+ | Positive supply rail | Accepts 2.7–6 V DC; supplies both amplifiers and shutdown circuitry; bypass with 0.1 µF ceramic. |

| 2IN− | Channel 2 inverting input | Electrically matched to Channel 1 inputs; enables dual-sensor or dual-path signal processing. |
| 2IN+ | Channel 2 non-inverting input | Provides second precision input pair; supports independent gain/offset calibration per channel. |
| NC | No internal connection | Pin 13 is unconnected - no routing or grounding required; electrically isolated. |
| 2SHDN | Channel 2 shutdown control | Independent active-high shutdown: enables selective power gating of Channel 2 only. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2463IDR | Same electrical specs, but in 14-pin SOIC (D) package with tape-and-reel delivery; thermal resistance θJA = 122.6°C/W vs. 78°C/W for N package. | Preferred for automated SMT assembly; less suitable for prototyping or through-hole legacy boards. | Select TLV2463IDR for volume production with pick-and-place; retain TLV2463AIN for hand-soldered evaluation or repair. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift, 0.1 µV offset); higher supply current (17 µA/ch); no shutdown function; 1.8–5.5 V supply. | Better DC accuracy for long-term sensor calibration; unsuitable where micropower shutdown or 6 V operation is required. | Choose OPA2333AIDR when sub-µV offset stability dominates over power; TLV2463AIN remains optimal for shutdown-aware, wide-VDD designs. |
Compared with TLV2463IDR, TLV2463AIN offers superior thermal performance in high-ambient environments due to lower θJA, while OPA2333AIDR trades 34× higher quiescent current for 500× lower offset drift - making TLV2463AIN the balanced choice for automotive and industrial applications demanding both precision and ultra-low-power control.

FAQ
What is the operating temperature range for TLV2463AIN?
The TLV2463AIN is rated for operation from −40°C to +125°C, meeting AEC-Q100 Grade 2 requirements for automotive under-hood and industrial control applications. This extended range is confirmed in the "Recommended Operating Conditions" table of the SLOS220J datasheet, where the "I-suffix" designation explicitly defines the −40°C to 125°C specification.
Does TLV2463AIN support true rail-to-rail input and output?
Yes, TLV2463AIN supports true rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 100 mV of both rails at 5 V). This is verified in the "Electrical Characteristics" tables for VOH/VOL and VICR parameters, and emphasized in the device description as a core differentiator versus prior-generation rail-to-rail op-amps.
What is the shutdown behavior of TLV2463AIN?
When the SHDN pin is pulled ≤0.7 V, TLV2463AIN enters ultralow-power shutdown mode drawing 0.3 µA per channel, and both outputs enter high-impedance state. This behavior is documented in the "Electrical Characteristics" table under IDD(SHDN) and confirmed in the functional description stating "output is placed in a high-impedance state" during shutdown.
Can TLV2463AIN drive a 100 pF load at unity gain?
Yes, TLV2463AIN maintains stability with 100 pF capacitive loads at unity gain, as evidenced by phase margin >44° and gain margin >7 dB in the "Operating Characteristics" table (CL = 160 pF test condition). The "Capacitive Load vs Load Resistance" plot (Figure 14) further confirms stable operation up to 1000 pF with appropriate resistive isolation.
What package type is TLV2463AIN supplied in?
TLV2463AIN is supplied in a 14-pin plastic DIP (N) package, as confirmed in the "TLV2462C/I/AI and TLV2463C/I/AI AVAILABLE OPTIONS" table where "TLV2463AIN" appears under the "PLASTIC DIP (N)" column with "−40°C to 125°C" temperature grade. Pinout matches the standard 14-pin DIP layout shown in Figure 4 of the datasheet.
