Programmable Switched Capacitor Filter (SCF) - Low pass, 10th order, root raised cosine
This module provides the user with an off-the-shelf programmable filter module capable of a wide range of filtering applications, where the desired cut-off frequency is either unknown by the user or the user requires a filter that can be reconfigured and re-used in a wide number of applications. By adjusting a single 11-turn variable resistor and setting 3 jumpers, the user of this module can select a cut-off frequency between 2kHz and 350kHz. The module can operate from double or single sided supplies and accepts differential or single-ended inputs.
Features:
- Single 11-turn variable resistor and jumpers set cut-off frequency
- External clock input facility via jumpers
- 10th order, linear phase, root raised cosine response
- Jumper selectable single sided or dual supply options
- Operates from 3V to 5V
- Over 300 kHz cut-off frequencies achievable on ±5v supplies (Isupply <= 33mA)
- Up to 300 kHz cut-off frequency on single 5v supply (Isupply <=22mA)
- Up to 150 kHz cut-off frequency on single 3v supply (Isupply <=10mA)
- DC accurate, typical Vos(max) = 5mV
- Differential or single-ended inputs
- Operating temperature range 0-70°C
Price: £60 per module
