Demonstration Board DC266A DC266A Description The DC266A DC266A board features LTC1562 LTC1562 and LTC1562-2 LTC1562-2 quad active RC filter building blocks. Assembly DC266A-A DC266A-A is available with the LTC1562 LTC1562 in a 20-pin SSOP package for very low noise and low distortion filter applications in the frequency range 10kHz to 150kHz. Assembly DC266A-B DC266A-B is available with the LTC1562-2 LTC1562-2 in a 20-pin SSOP package for very low noise and low distortion filter applications in the frequency range 50kHz to 300kHz. A DC266A-A DC266A-A or a DC266A-B DC266A-B board has two sections, SECTION A and SECTION B. SECTION A of a DC266A DC266A board is assembled with a filter IC (LTC1562 LTC1562 or LTC1562-2 LTC1562-2) in a 20-pin SSOP package with power supply decoupling capacitors and on the board jumpers for dual or single supply operation and power shutdown. Also provided are pads for 0805 size surface mount resistors and capacitors and terminals for filter inputs, outputs and power supply. The printed circuit layout of a DC266A-A DC266A-A or a DC266A-B DC266A-B assembly allows SECTION A to be configured as single eighth order filter or as dual fourth order filters. SECTION B of a DC266A DC266A board has a printed circuit layout for a dual op amp configured as two inverting summing amplifiers with a feedback capacitor. Applications Single 8th order or dual 4th order low noise filters. Frequency range 10kHz to 300kHz. Lowpass, Bandpass, Highpass, Notch, Allpass or Arbitrary response.
