Implantable devices including pacemakers, cardiac defibrillators, neurostimulators, pumps, and cochlear and optical implants require sensor, analog/mixed signal processing, wireless, and power management technology to solve performance, power, size, and reliability challenges. Analog Devices offers a broad portfolio of signal processing technologies that address these implantable design requirements including:

• MEMS sensors such as the ADXL345 3-axis accelerometer that combines low power down to 25uA, precision up to 13-bits, and integrated FIFO in a small 3mm × 5mm × 1mm package.
• Instrumentation amplifiers including the AD8235 that offers 40uA supply current with 6nA shutdown current in a 1.5mm × 2mm package.
• Microcontrollers that combine precision analog functions such as 24-bit sigma-delta ADCs and 12-bit DACs, temperature sensor, voltage reference, Flash (up to 126kB), and RAM (up to 8kB) with an ARM7 processor.
