Product details
Overview
TLV2462QDG4 from Texas Instruments is a dual, rail-to-rail input/output operational amplifier designed for low-voltage 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 ADC inputs in battery-powered sensor interfaces.
For engineers reviewing the TLV2462QDG4 datasheet, TLV2462QDG4 pinout, TLV2462QDG4 application, or TLV2462QDG4 equivalent, this device is selected for precision analog front-ends where rail-to-rail swing, low quiescent current, and Q-temp automotive qualification (−40°C to 125°C) are mandatory - especially in engine control units, ADAS sensor signal chains, and industrial data acquisition systems.
Technical Context
The TLV2462QDG4 integrates two 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. Its 6.4 MHz GBW and 1.6 V/µs slew rate support stable unity-gain buffer operation up to ~1 MHz with 10 kΩ load and 160 pF capacitive load.
Each channel features an active shutdown terminal (SHDN) that reduces supply current to 0.3 µA per channel while placing the output in high-impedance state. The device operates from 2.7 V to 6 V single supply (or ±1.35 V to ±3 V split supply), meeting automotive Q-temp requirements with specified performance across −40°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop gain ≥10 up to ~600 kHz with minimal phase margin degradation |
| Slew Rate | 1.6 V/µs - enables full-scale 2 VPP output at 500 kHz without slewing distortion |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.004% gain error in 2.5 V full-scale 12-bit ADC reference buffers |
| Supply Current / Channel | 500 µA - allows dual-channel operation under 1 mA total, critical for always-on automotive subsystems |
| Output Drive | ±80 mA - drives 62 Ω loads to rails, sufficient for driving SAR ADC sample-and-hold inputs directly |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - contributes <1.5 µVRMS integrated noise in 10 kHz bandwidth, preserving SNR in sensor amps |
| Shutdown Current | 0.3 µA/channel - enables microamp-level system sleep mode without external power gating |
Pinout & Package
TLV2462QDG4 is housed in an 8-pin SOIC (D) package with exposed thermal pad (DG4 suffix denotes SOIC-8 with thermal enhancement). Pinout follows standard dual op-amp configuration with independent shutdown control per channel.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - rail-to-rail capable, ±80 mA sink/source, high-Z in shutdown |
| 2 | IN− A | Inverting input - rail-to-rail common-mode range (0 V to VDD), 1.3 nA bias current @ 5 V |
| 3 | IN+ A | Non-inverting input - same rail-to-rail CMVR as IN−, matched to IN− for low offset |
| 4 | GND | Analog ground reference - shared return path for both channels and shutdown logic |
| 5 | SHDN A | Channel A shutdown enable - driven >2 V to enable, <0.7 V to disable (0.3 µA IDD) |
| 6 | VDD+ | Positive supply - accepts 2.7–6 V single supply or +VDD in split-supply configurations |
| 7 | OUT B | Channel B output - electrically identical to OUT A, independent of Channel A operation |
| 8 | IN− B | Inverting input for Channel B - fully isolated from Channel A; no crosstalk specified |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V and 5 V systems without level-shifting circuitry |
| Q-temp automotive qualification | Guaranteed operation and parametric limits over −40°C to 125°C ambient, per AEC-Q100 stress testing |
| Independent per-channel shutdown | Reduces system standby power by disabling unused channel without affecting active signal path |
| Low input offset drift | 2 µV/°C tempco ensures <200 µV offset shift over full temperature range, critical for precision DC sensing |
| High CMRR & PSRR | 85 dB CMRR and 85 dB PSRR minimize error from supply ripple and common-mode interference in noisy environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Same silicon, but I-suffix (−40°C to 125°C) in SOIC-8 without thermal pad; 550 µA/channel IDD, 150 µV VIO max | Qualified for industrial, not automotive; lacks Q-temp documentation and AEC-Q100 traceability | Select when automotive qualification is unnecessary and cost sensitivity outweighs thermal performance |
| OPA2333AIDGKR | Zero-drift architecture; 0.02 µV/°C offset drift, 60 µV VIO max, 17 µA/channel IDD, 350 kHz GBW | Superior DC precision but lower speed; unsuitable for >100 kHz AC-coupled signal paths | Select for ultra-low-drift DC applications (e.g., precision weigh scales) where bandwidth <200 kHz suffices |
Compared with TLV2462IDR, TLV2462QDG4 provides verified automotive qualification and enhanced thermal dissipation; compared with OPA2333AIDGKR, it trades zero-drift stability for 18× higher bandwidth and 30× higher output drive - making it optimal for mixed-signal automotive front-ends requiring both precision and speed.

FAQ
What is the operating temperature range certified for TLV2462QDG4?
The TLV2462QDG4 is qualified for operation from −40°C to 125°C ambient temperature and is documented to meet AEC-Q100 stress test requirements for automotive applications. This Q-temp rating is explicitly confirmed in TI's SLOS220J datasheet revision February 2004, and applies to all electrical parameters across the full range without derating.
Does TLV2462QDG4 support true rail-to-rail input and output simultaneously?
Yes, TLV2462QDG4 supports rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 10 mV of each rail at ±80 mA load). This is verified in the "Electrical Characteristics" tables for both VOH and VOL at 2.7 V and 5 V supplies, and confirmed in Figure 5–8 of the datasheet showing output voltage vs. load current.
How does the shutdown function behave on TLV2462QDG4?
TLV2462QDG4 provides independent shutdown control for each channel via dedicated SHDN pins (Pin 5 for Channel A, Pin 10 for Channel B). When SHDN is pulled below 0.7 V, that channel draws only 0.3 µA supply current and its output enters high-impedance state - verified in the "Electrical Characteristics" table under IDD(SHDN) with test condition SHDN < 0.7 V.
What is the maximum capacitive load TLV2462QDG4 can drive stably?
TLV2462QDG4 maintains ≥30° phase margin driving up to 160 pF capacitive load with 10 kΩ resistive load, as shown in Figure 36 ("Phase Margin vs Load Capacitance") and confirmed in the "Operating Characteristics" table (Slew Rate test condition CL = 160 pF). For loads >160 pF, external isolation resistor is recommended.
Is TLV2462QDG4 pin-compatible with other devices in the TLV246x family?
TLV2462QDG4 uses the standard 8-pin SOIC (D) package with identical pinout to TLV2462IDR, TLV2462CDR, and TLV2462AIDR - all share Pin 1 = OUT A, Pin 2 = IN− A, Pin 3 = IN+ A, Pin 4 = GND, Pin 5 = SHDN A, Pin 6 = VDD+, Pin 7 = OUT B, Pin 8 = IN− B. No PCB changes are required when substituting within the TLV2462x D-package variants.
