MAXQ3120
Applications Information
The low-power, high-performance RISC architecture of
the MAXQ3120 makes it an excellent fit for many
portable or battery-powered applications that require
cost-effective computing. The high-throughput core is
complemented by a dual-differential channel, 16-bit
sigma-delta ADC, and 16-bit hardware multiplier-accu-
mulator, allowing the implementation of sophisticated
computational algorithms. Applications benefit from a
wide range of peripheral interfaces, allowing the micro-
controller to communicate with many external devices.
With integrated LCD support of up to 112 segments (4 x
28), applications can support complex user interfaces.
Displays are driven directly with no additional external
hardware required. Contrast can be adjusted using a
built-in, adjustable resistor. The simplified architecture
reduces component count and board space, critical
factors in the design of portable systems.
The MAXQ3120 is ideally suited for single-phase elec-
tricity metering applications as well as other applica-
tions that require high-precision analog-to-digital
conversion and signal processing.

Definitions
Offset Error
For an ideal converter, the first transition occurs at 0.5
LSB above zero. Offset error is the amount of deviation
between the measured first transition point and the
ideal point.
Gain Error
With a full-scale analog voltage applied to the ADC
(resulting in all ones in the digital code), gain error is
defined as the amount of deviation between the ideal
transfer function and the measured transfer function
(with the offset error removed). Gain error is usually
expressed in LSB or as a percentage of full-scale
range (%FSR).
Power-Supply Rejection Ratio
Power-supply rejection ratio (PSRR) is the ratio of
changes in the power supply (V) to changes in the con-
verter output (V). It is typically measured in decibels.
