MAXQ8913

19-4605; Rev 0; 6/09 www.DataSheet4U.com 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 conditioning of sensor signals, analog-to-digital conversion, digital 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 applications, 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 memory, 4KB of RAM, 4KB of ROM, a 16-bit timer/counter, a universal asynchronous/synchronous receiver-transmitter (USART), an I2C 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-saving operating modes.
