Description

The COS6171 is a single rail-to-rail 6-pole output reconstruction filter with a -3dB bandwidth of 8MHz and a slew rate of 43V/μs. The DP171 has a built-in SAG

correction circuit which significantly reduces the size of the output coupling capacitor when used in an output AC-coupled mode.

Operating from single supply ranging from 3V to 5.5V and sinking an ultra-low 7mA quiescent current, the DP171 is ideally suited for low power, battery-operated applications. To further reduce power

consumption, an enable pin is provided. The DP171 is specified over the extended -40°C to +85°C temperature range and

available in a space saving SOT23-6 package.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device

reliability. The absolute maximum ratings are stress ratings only.
