DC393B

DC393B evaluation board is for the LTC1564 digitally controlled amplifier and filter. The LTC1564 is a continuous time 8th order lowpass filter with cut-off 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 4bit gain 1-16 and 4bit bandwidth inputs (Linduino DC2026 is an Analog Devices trademark). The DC393B input is a low noise, high impedance buffer (LT6233) jumper configurable for gains two or ten and the output is a buffer (ADA4807-1) for driving an AD7980, AD4004 or equivalent SAR ADC.
