Medical ASIC Applications


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
 

Hearing Aid

This is an advanced custom ASIC hearing aid. When mated with input and output transducers, it provides audio amplification and frequency response correction. An internal EEPROM stores trim and configuration data. It operates at low supply voltage and current. This IC was developed in conjunction with a leading manufacturer of advanced hearing aids.

Features
  • Low Minimum Supply Voltage (1.5V)
  • Low Active Current
  • Adjustable Gain
  • Adjustable Frequency Response
  • Internal EEPROM
  • Serial Interface
  • Temperature Range = 0°C to +70°C
 

Biometric Monitor

This IC monitors a variety of biometric parameters. Typical parameters include: pressure, temperature, ECG, EMG, EEG and EOG data. Each system is wireless. A transmitter and battery allow un-tethered data collection. This IC was developed in conjunction with a leading manufacturer of advanced biometric monitoring devices.
