Analog Devices ADuCM350
Data Sheet
GENERAL DESCRIPTION
The ADuCM350 is a complete, coin cell powered, high
precision, meter-on-chip for portable device applications for
applications such as point-of-care diagnostics and body-worn
devices for monitoring vital signs. The ADuCM350 is designed
for high precision amperometric, voltametric, and impedometric
measurement capabilities.
The ADuCM350 analog front end (AFE) features a 16-bit,
precision, 160 kSPS analog-to-digital converter (ADC); 0.17%
precision voltage reference; 12-bit, no missing codes digital-to-
analog converter (DAC); and a reconfigurable ultralow leakage
switch matrix. The ADuCM350 also includes an ARM® Cortex-
M3-based processor, memory, and all I/O connectivity to
ADuCM350
support portable meters with display, USB communication, and
active sensors. The ADuCM350 is available in a 120-lead, 8 mm
× 8 mm CSP_BGA and operates from −40°C to +85°C.
To support extremely low dynamic and hibernate power
management, the ADuCM350 provides a collection of power
modes and features, such as dynamic and software controlled
clock gating and power gating.
The AFE is connected to the ARM Cortex-M3 via an advanced
high performance bus (AHB) slave interface on the advanced
microcontroller bus architecture (AMBA) matrix, as well as
direct memory access (DMA) and interrupt connections.
