MCP3910A1T-E/ML規(guī)格書詳情

MCP3910A1T-E/ML屬于集成電路(IC)的電能計(jì)量。由微芯科技股份有限公司制造生產(chǎn)的MCP3910A1T-E/ML電能計(jì)量能量計(jì)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(cè)量。這些器件可以測(cè)量線路電壓和電流,并且可以計(jì)算有功、無功和視在電能,以及瞬時(shí)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.
