Texas Instruments LM358LVIDDFR Overview

The Texas Instruments LM358LVIDDFR is a dual-channel, low-power operational amplifier designed for a broad range of general-purpose analog applications. As a member of the LM358LV family, it is optimized for low-voltage operation and features rail-to-rail output, low quiescent current, and a wide temperature range. The device is well-suited for portable, battery-powered systems, signal conditioning, active filtering, and control applications where space and power efficiency are crucial. It is packaged in a compact 8-pin SOIC (DDF) package.

Low-Voltage Operation and Supply Flexibility

The LM358LVIDDFR is designed to operate from a single-supply voltage as low as 2.7 V, making it compatible with modern low-voltage digital logic systems. It also supports dual-supply configurations, giving designers flexibility in both legacy and contemporary designs.

* Supply Voltage Range (Single Supply): 2.7 V to 5.5 V
* Supply Voltage Range (Dual Supply): ±1.35 V to ±2.75 V
* Common-Mode Voltage Range: From V– to (V+ – 1 V)
* Power Supply Rejection Ratio (PSRR): 95 dB (typical)

Low Power Consumption

The LM358LVIDDFR is built with low-power operation in mind, making it ideal for energy-sensitive applications such as handheld devices and sensor interfaces. Its quiescent current is low enough to maintain long battery life without sacrificing performance.

* Quiescent Current (Per Amplifier): 80 µA (typical)
* Total Supply Current (Both Channels): ~160 µA (typical)
* Shutdown Mode: Not available (always active)

Performance Characteristics

While optimized for low-power operation, the LM358LVIDDFR maintains good analog performance with sufficient gain bandwidth and slew rate for a wide range of signal conditioning and control loop tasks. It also features output swing close to the rails, which simplifies design in low-voltage systems.

* Gain Bandwidth Product: 1 MHz (typical)
* Slew Rate: 0.3 V/µs (typical)
* Input Offset Voltage: ±2 mV (typical), ±7 mV (max)
* Input Bias Current: 2 pA (typical)
* Input Offset Drift: 5 µV/°C (typical)
* Output Voltage Swing: 0 V to V+ – 0.05 V (typical with 10 kΩ load)
* CMRR (Common Mode Rejection Ratio): 80 dB (typical)
* Output Drive Capability: ±20 mA (typical)

Input and Output Capabilities

The input stage supports signals down to the negative rail (ground in single-supply mode), and the output is capable of swinging very close to both rails, which is essential for low-headroom applications. While it is not fully rail-to-rail on the input, it is capable of handling a significant portion of the input voltage range.

* Input Voltage Range: Includes ground
* Output Rail-to-Rail: Yes (close to both rails)
* Output Impedance: Low, supporting capacitive loads with reasonable stability

Protection and Reliability Features

While the LM358LVIDDFR does not include advanced fault protections like overvoltage protection or thermal shutdown, it is internally ESD-protected and built to operate reliably in industrial and consumer environments.

* ESD Protection (HBM): ±4000 V
* Operating Temperature Range: –40°C to +125°C
* Latch-Up Immunity: 100 mA per JESD78
* RoHS Compliant: Yes
* Moisture Sensitivity Level: MSL 1 (unlimited floor life at ≤30°C/85% RH)

Package and Pin Configuration

The LM358LVIDDFR is housed in a standard 8-pin SOIC package, which is widely used and compatible with automated assembly processes.

* Package Type: SOIC-8 (DDF)
* Pin Count: 8
* Pin Pitch: 1.27 mm
* Package Dimensions: 5.0 mm × 4.0 mm
* Mounting: Surface Mount
* Thermal Resistance (θJA): ~130°C/W
