The SBE811-TL-E is a low-power, low-noise, radiation-hardened, dual-channel digital attenuator produced by ON Semiconductor. This device is designed to operate over a wide range of operating temperature ranges, including -55°C–125°C. The device features a wide tuning range, up to 42 dB of attenuation in 0.5 dB steps, and a high-precision TTL/CMOS compatible control interface that operates with I2C or SPI protocols. The device is also equipped with digital lock capability and ESD protection. Additionally, it has a power supply range from 3.3 V–14V and is packaged in a hermetically sealed ceramic flatpack.
