DC393B

Features and Benefits

The DC393B evaluation board is for the LTC1564 digitally controlled amplifier and filter. The LTC1564 is a continuous time 8th order lowpass filter with cutoff frequency (fc) and gain digitally controlled. The LTC1564 is a rail-to-rail elliptic 8th-order lowpass filter giving approximately 100dB attenuation at 2 .5 x fc. Signals with low or variable levels can be normalized with the built-in variable gain that reduces input-referred noise with increasing gain for a maximum signal level to noise, SNR. A DC393B can be used stand-alone with external control of the LTC1564 digital inputs or as a Linduino shield controls the LTC1564 4-bit gain 1-16 and 4-bit bandwidth inputs (Linduino DC2026 is an Analog Devices trademark).
