Custom Mixed Signal Medical ASICs

A selection of custom mixed signal Medical ASICs from Custom Silicon Solutions, including Hearing Aids and a Biometric Monitor.

 
Hearing Aid (Audio Tapered Pot)

This Custom ASIC provides four audio tapered trim pots for adjusting gain and filter response in hearing aids. The setting for each pot is stored in EEPROM and is accessed via a two wire serial interface. Unique low voltage analog switches are used to provide a rail-to-rail input range at supply voltages of just 1.1V.

Features

  • Low Minimum Supply Voltage (1.1V)
  • Ultra Low Supply Current (< 1uA)
  • Audio Tapered Trim Pots
  • 4 Independent channels
  • Resolution = 7 or 8 bits (2 of each)
  • Internal 30 Bit EEPROM
  • 2 Wire Serial Interface
  • Temperature Range = 0°C to +70°C
