Product details
Overview
TLV2461CDBVRG4 from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 100 µV input offset voltage, and 11 nV/√Hz input noise voltage - enabling high-fidelity signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2461CDBVRG4 datasheet, TLV2461CDBVRG4 pinout, TLV2461CDBVRG4 application, or TLV2461CDBVRG4 equivalent, this device is selected for precision analog signal conditioning where rail-to-rail swing, micropower operation (500 µA/channel), and shutdown capability (0.3 µA/channel) are critical in battery-powered instrumentation and industrial sensing nodes.
Technical Context
The TLV2461CDBVRG4 employs a complementary input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing - critical for maximizing dynamic range in 2.7–6 V single-supply systems. Its internal architecture supports stable unity-gain operation with 45° phase margin at 10 kΩ load and 160 pF capacitive load.
It integrates a dedicated SHDN terminal that places the amplifier in ultralow-current mode (0.3 µA/channel) while forcing output into high-impedance state - eliminating loading during power-down without external switches. DC precision is maintained via 100 µV max input offset voltage and 2 µV/°C drift over −40°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~500 kHz at gain = 10 without excessive phase lag. |

| Supply Current per Channel | 500 µA - allows continuous operation in sub-1 mA system power budgets for portable sensors. |
| Input Offset Voltage | 100 µV - ensures <0.01% gain error in 1 V full-scale 12-bit ADC driver applications. |
| Rail-to-Rail I/O | Input common-mode range: 0 V to VDD; Output swing: within 100 mV of rails - maximizes usable signal headroom in 3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces total system standby current by >99% vs active mode, critical for wake-on-event architectures. |
| Output Drive | ±80 mA - drives 10 kΩ loads with <0.1% THD+N at 1 kHz and supports direct interface to SAR ADC reference buffers. |

FAQ
What is the operating temperature range for TLV2461CDBVRG4?
The TLV2461CDBVRG4 is specified for operation from 0°C to 70°C (C-suffix grade). This makes it suitable for commercial and consumer-grade portable electronics, including handheld test equipment and battery-powered sensors where ambient temperatures remain within this range. It is not qualified for automotive under-hood or extended industrial environments.
Does TLV2461CDBVRG4 support true rail-to-rail input and output?
Yes, TLV2461CDBVRG4 supports true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 100 mV of each rail at ±80 mA load). This is confirmed in the datasheet's "Common-mode input voltage range" and "Output voltage swing" specifications, enabling full dynamic range utilization in 3 V and 5 V single-supply systems.
How does the shutdown feature of TLV2461CDBVRG4 behave electrically?
When the SHDN pin is pulled below 0.7 V, TLV2461CDBVRG4 enters shutdown mode drawing only 0.3 µA per channel, and its output transitions to high-impedance state. When SHDN rises above 2 V, the amplifier resumes normal operation with typical turnon time of 7.65 µs. This behavior is explicitly characterized in the "Operating Characteristics" table on page 8 of the datasheet.
Can TLV2461CDBVRG4 drive a 10 kΩ load at 3 V supply with rail-to-rail output?
Yes - TLV2461CDBVRG4 delivers rail-to-rail output swing into 10 kΩ loads at 3 V supply, with high-level output voltage ≥2.8 V and low-level output voltage ≤0.2 V (per datasheet Table 7, VDD = 3 V, IOL/IOH = 2.5 mA). This meets standard 12-bit ADC interface requirements without external level-shifting circuitry.
What is the maximum capacitive load TLV2461CDBVRG4 can drive stably?
TLV2461CDBVRG4 maintains ≥30° phase margin driving up to 160 pF capacitive load with 10 kΩ resistive load (per Figure 36 and page 10 characterization). For loads exceeding 160 pF, external isolation resistance (e.g., 10–50 Ω series resistor) is recommended to ensure stability in ADC driver or filter applications.
