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
2
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.
