  1. Default Phonon Front End (No change in active components from Rev A) LNA PGA Av@100 Av=1..7 Vzap AD797 Squid Phonon LT6910 Squid Bias 3 Gain Sel Avdc@4 PGA Av=1..7 LT6910 3 Squid FB Gain Sel FB Synthesizer AD8130

  2. Option: Use LMP8100 LNA PGA Av@100 Av=1..7 Vzap AD797 Squid Phonon LT6910 Squid Bias 3 Gain Sel Avdc@4 PGA Av=1..16 LMP8100 3 Squid FB SPI FB Synthesizer The good: Extended gain range, fewer control wires The bad: Requires ±2.5V Power AD8130

  3. Option: Use AD8337 LNA PGA Av@100 Av=1..7 Vzap AD8337 LNA Squid Phonon LT6910 Squid Bias 3 Gain Sel VGA Avdc@4 Av=-6..+18db AD8337 VGA 1 Squid FB VGain (24db range) FB Synthesizer The good: Extended gain range, small footprint, fewer chips The bad: Higher power, marginal noise performance, unknown 1/F corner, requires a DAC channel for gain setting AD8130

  4. Option: use AD8250 LNA PGA Av@100 Av=1..7 Vzap AD797 Squid Phonon LT6910 Squid Bias 3 Gain Sel PGA Av=1,2,5,10 FB Synthesizer Squid FB Av=~10 AD8066(e.g.) 2 Gain Sel AD8250 The good: Flexible topology, small footprint, fewer control wires The bad: Limited gain range, 2 devices don’t have enough gain
