Fast Data Rates Meet High Accuracy in Microchip’s New Analog-to-Digital Converter Families
June 20 2019 - 8:00AM
The rapidly growing market of high precision applications requires
Analog-to-Digital Converters (ADCs) with faster programmable data
rates, higher accuracy and more integrated features to maximize
system performance. To meet these needs, Microchip Technology Inc.
(Nasdaq: MCHP) today introduced a family of
compact ADCs that offer high programmable data rates of up to 153.6
kilosamples per second (kSPS). The
24-bit MCP356x and
16-bit MCP346x delta-sigma ADC families offer faster
programmable data rates over similar devices on the market while
providing high accuracy and lower noise performance. Available in a
tiny 3 mm x 3 mm UQFN-20 package, these highly integrated ADCs meet
increasing demand for small packaging in space-constrained
applications such as portable instrumentation devices.
Most high-resolution delta-sigma ADCs on the market
have slower programmable data rates of a few kSPS. The MCP356x and
MCP346x families offer a much faster data rate, making the devices
ideal for a variety of precision applications that require
different data speeds, including industrial process control,
factory automation and sensor transducers and transmitters. The
ADCs also offer integrated features to eliminate the need for
external components and reduce the overall cost of a system,
including an internal oscillator, temperature sensor and burnout
current source.
“Accuracy is often sacrificed in ADCs that offer
high resolution and faster data rates,” said Bryan J. Liddiard,
vice president of Microchip’s mixed-signal and linear business
unit. “These devices offer much faster programmable speeds while
maintaining the high accuracy that precision applications depend
on.”
The new families provide 24-bit or 16-bit
resolution, two/four/eight single-ended or one/two/four
differential channel options, allowing developers to choose the
most suitable ADC for their designs. The devices join Microchip’s
extensive portfolio of versatile ADCs that meet the needs of a
variety of speed, accuracy and power consumption requirements.
Development ToolsThe MCP3564 ADC evaluation kit
(ADM00583) is available to demonstrate the performance of the
MCP356x family. The kit includes the following components:
- MCP3564 ADC Evaluation Board for PIC32 MCUs (ADM00583)
- PIC32MX795F512L PIM
- USB Cable
Pricing and AvailabilityThe MCP356x and MCP346x
ADC devices are available today in 3 mm x 3 mm UQFN-20 packages.
Options and pricing for 10,000-unit quantities are as follows:
- MCP3561 (24-bit, two-channel): $1.82 each
