16-Bit, Mixed-Signal Microcontroller with Op Amps,

ADC, and DACs for All-in-One Servo Loop Control

General Description

The MAXQ8913 is a single-chip servo controller

designed as a complete solution for dual axis optical

image stabilization (OIS) applications. The device

incorporates all the necessary elements for condition-

ing of sensor signals, analog-to-digital conversion, digi-

tal servo algorithm implementation using a 16-bit RISC

microcontroller, and digital-to-analog conversion, as

well as including dual servo amplifiers.

Even though the device is targeted for OIS applica-

tions, it can be effectively used in many other types of

servo control. The MAXQ8913 supports both voice coil

and stepper motor applications.

The MAXQ8913 includes four op amps; a 7-channel,

12-bit ADC; dual 10-bit differential DACs; and dual 8-bit

single-ended DACs. It also contains 64KB of flash mem-

ory, 4KB of RAM, 4KB of ROM, a 16-bit timer/counter, a

universal asynchronous/synchronous receiver-transmit-

ter (USART), an I

C port, and an SPI™ master/slave

port.

For the ultimate in low-power performance, the OIS

device includes a low-power sleep mode, the ability to

selectively disable peripherals, and multiple power-sav-

ing operating modes.
