The BA3835F-E2 is a silicon monolithic integrated circuit band pass filter designed for spectrum analyzers in car audio systems. It features five selectable filter bands with center frequencies at 105Hz, 340Hz, 1kHz, 3.4kHz, and 10.5kHz, controlled by three logic inputs (A, B, C) and a SEL pin. The device operates from a 4.5V to 6.5V supply voltage, typically drawing 8.5mA of current.
Each filter band provides a standard output level of 1.35V typical (0.65V min, 1.70V max) under specified test conditions. The input impedance is 100kΩ typical, and the common mode rejection ratio is 50dB typical. The output response time is 5μs typical, and the device includes a reset function with a 10μs pulse width.
The BA3835F-E2 is available in an 18-SOP surface mount package (18-SOIC, 0.213" width) and supports an operating temperature range of -25°C to 75°C. Power dissipation is 450mW maximum with derating above 25°C. The device is designed for 5V microcontroller-based systems and is suitable for automotive audio applications.
The operating voltage range is 4.5V to 6.5V, with a typical value of 5.0V at 25°C.
It is available in an 18-SOP surface mount package (18-SOIC, 0.213" width).
The operating temperature range is -25°C to 75°C.
The RoHS status is listed as RoHS3 Compliant, but this is unverified and should be confirmed with official documentation.
It has 5 filter bands with center frequencies at 105Hz, 340Hz, 1kHz, 3.4kHz, and 10.5kHz.
The typical circuit current is 8.5mA, with a maximum of 13mA under specified conditions.
The input impedance is 100kΩ typical, with a range of 80kΩ to 120kΩ at 1kHz.
