Product details
Overview
TLV2462CDG4 from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-voltage portable systems, delivering 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, and ±80 mA output drive at 500 µA/channel supply current. It features micropower shutdown (0.3 µA/channel), 100 µV input offset voltage, and 11 nV/√Hz input noise voltage - enabling high-fidelity analog signal conditioning in battery-powered ADC buffering and sensor front-ends.
For engineers reviewing the TLV2462CDG4 datasheet, TLV2462CDG4 pinout, TLV2462CDG4 application, or TLV2462CDG4 equivalent, key selection considerations include its MSOP-8 package with integrated shutdown control, −40°C to 125°C industrial temperature range, rail-to-rail output swing down to 100 mV from rails at 10 mA load, and verified performance in single-supply 2.7–6 V operation without external level-shifting circuitry.
Technical Context
The TLV2462CDG4 implements a complementary input stage enabling true rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing. Its internal architecture supports stable unity-gain operation with 160 pF capacitive load and delivers 45° phase margin at 5 V supply.
Shutdown functionality is TTL-compatible: applying SHDN < 0.7 V places both amplifiers into ultralow-current state (0.3 µA/channel), while output transitions to high-impedance - preserving signal integrity in power-gated subsystems without requiring external isolation switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to 100 kHz with gain ≥ 64, suitable for anti-aliasing filters and active sensor conditioning. |
| Slew Rate | 1.6 V/µs - supports 10-bit ADC sampling at 1 MSPS with ≤0.5 LSB dynamic error in buffer configuration. |
| Supply Current per Channel | 500 µA - allows continuous operation for >1 year on a 200 mAh coin cell in always-on sensor nodes. |
| Input Offset Voltage | 100 µV - ensures ≤0.002% full-scale error in 5 V-range precision instrumentation amplifiers. |
| Output Drive Capability | ±80 mA - drives 60 Ω loads directly (e.g., coaxial cable termination) without external buffers. |
| Rail-to-Rail Output Swing | Within 100 mV of rails at 10 mA - preserves >98% dynamic range in 3.3 V ADC interfaces. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode in duty-cycled measurement systems. |
Pinout & Package
TLV2462CDG4 is housed in an 8-pin MSOP (DGK) package with 0.65 mm pitch, 3.0 mm × 3.0 mm footprint, and exposed thermal pad for enhanced power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; capable of sourcing/sinking ±80 mA into resistive or capacitive loads. |
| 2 (IN− A) | Inverting input A | Differential input node with 1300 pA bias current; accepts common-mode voltages from GND to VDD. |
| 3 (IN+ A) | Non-inverting input A | High-impedance input (10⁹ Ω) for precision voltage sensing; matched to IN− A for low offset drift. |
| 4 (GND) | Analog ground reference | Primary return path for both amplifiers and shutdown logic; requires low-impedance PCB connection to minimize noise coupling. |
| 5 (SHDN) | Shutdown control input | TTL-compatible enable: <0.7 V disables both amps (0.3 µA total IDD); >2 V enables normal operation. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply or ±1.35–±3 V split supply; internal regulation ensures stable bias over voltage transients. |
| 7 (IN+ B) | Non-inverting input B | Independent high-Z input for second channel; electrically isolated from Channel A except shared supply and ground paths. |
| 8 (OUT B) | Amplifier B output | Identical performance to OUT A; supports independent gain/feedback networks for dual-path signal processing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Same electrical specs but rated for −40°C to +125°C (I-suffix) and supplied in tape-and-reel (R-suffix); no DG4 suffix marking. | Preferred for automotive under-hood modules requiring extended temperature qualification and automated assembly compatibility. | Select TLV2462IDR when AEC-Q100 stress testing or SMT production volume >10k units/year is required. |
| OPA2340UA | Higher GBW (10 MHz) and lower noise (8 nV/√Hz), but higher supply current (800 µA/ch) and no shutdown function. | Better suited for wideband active filters or high-speed photodiode transimpedance amps where power budget permits. | Choose OPA2340UA only if bandwidth >8 MHz or noise <9 nV/√Hz is mandatory and shutdown is unnecessary. |
Compared with TLV2462CDG4, TLV2462IDR offers identical performance with enhanced temperature rating and packaging for high-reliability manufacturing, while OPA2340UA trades 60% higher quiescent power for 56% greater bandwidth and 27% lower noise - making TLV2462CDG4 optimal for battery-constrained, temperature-stable dual-channel signal conditioning.

FAQ
What is the maximum capacitive load the TLV2462CDG4 can drive stably?
The TLV2462CDG4 maintains stability with up to 160 pF capacitive load at unity gain (AV = 1) and 5 V supply, achieving 45° phase margin. For loads exceeding 100 pF, TI recommends adding a 10–50 Ω series resistor between the output and capacitor to isolate the reactive load and preserve transient response fidelity in TLV2462CDG4-based circuits.
Does the TLV2462CDG4 support single-supply operation below 3 V?
Yes, the TLV2462CDG4 is fully specified for single-supply operation from 2.7 V to 6 V. At 2.7 V, it retains rail-to-rail input common-mode range (0 V to 2.7 V), 100 µV typical input offset voltage, and 1.6 V/µs slew rate - enabling accurate signal acquisition in energy-harvesting systems powered by 2.8 V thin-film batteries or supercapacitors.
How does the shutdown feature affect output state in TLV2462CDG4?
When SHDN is pulled below 0.7 V, both amplifiers enter ultralow-current mode (0.3 µA/channel total), and their outputs transition to high-impedance (Hi-Z) state - not tri-state or forced to mid-rail. This prevents loading of downstream circuits during sleep, eliminates shoot-through current in multiplexed sensor arrays, and avoids false triggering in TLV2462CDG4-driven comparators or ADC sample-and-hold inputs.
What is the input bias current specification for TLV2462CDG4 at 25°C and 5 V supply?
At 25°C and 5 V supply, the TLV2462CDG4 exhibits a typical input bias current of 1.3 nA (max 14 nA) and input offset current of 0.3 nA (max 7 nA). These values are measured with VIC = 2.5 V and RS = 50 Ω, confirming suitability for high-impedance pH electrode interfaces, piezoelectric sensor amplifiers, and photodiode transimpedance configurations where leakage-induced errors must remain below 100 µV.
Can TLV2462CDG4 be used in inverting amplifier configurations with gain >100?
Yes, the TLV2462CDG4 supports inverting gains up to 1000 at DC and low frequencies, but gain-bandwidth trade-offs limit small-signal bandwidth: at AV = −100, usable bandwidth is ~64 kHz (6.4 MHz ÷ 100). For high-gain precision applications, TI recommends using matched metal-film feedback resistors and guarding the inverting node to mitigate noise and parasitic capacitance effects in TLV2462CDG4 designs.
