MCP3910A1T-E/ML規(guī)格書詳情
MCP3910A1T-E/ML屬于集成電路(IC)的電能計量。由微芯科技股份有限公司制造生產(chǎn)的MCP3910A1T-E/ML電能計量能量計量集成電路可用于單相、雙相和三相電力線系統(tǒng)中的高精度電能測量。這些器件可以測量線路電壓和電流,并且可以計算有功、無功和視在電能,以及瞬時均方根電壓和電流。
Description:
The MCP3910 is a 3V two-channel Analog Front End
(AFE), containing two synchronous sampling
Delta-Sigma, Analog-to-Digital Converters (ADC), two
Programmable Gain Amplifiers (PGA), phase delay
compensation block, low-drift internal voltage
reference, Digital Offset and Gain Errors Calibration
registers and high-speed 20 MHz SPI-compatible
serial interface.
The MCP3910 ADCs are fully configurable with
features such as: 16-/24-bit resolution, Oversampling
Ratio (OSR) from 32 to 4096, gain from 1x to 32x,
independent shutdown and Reset, dithering and
auto-zeroing. Communication is largely simplified with
8-bit commands, including various continuous Read/
Write modes and 16-/24-/32-bit data formats that can
be accessed by the Direct Memory Access (DMA) of an
8, 16 or 32-bit MCU. It also includes a separate Data
Ready pin that can directly be connected to an Interrupt
Request (IRQ) input of an MCU.
The MCP3910 includes advanced security features to
secure the communications and the configuration settings,
such as a CRC-16 checksum on both serial data
outputs and on the static register map configuration. It
also includes a register map lock through an 8-bit
password to stop unwanted WRITE commands from
processing.
For polyphase shunt-based energy meters, the
MCP3910 two-wire serial interface greatly reduces
system cost, requiring only a single bidirectional
isolator per phase.
The MCP3910 is capable of interfacing a variety of voltage
and current sensors, including shunts, current
transformers, Rogowski coils and Hall effect sensors.
