Data Converters

Delta-Sigma Analog-to-Digital Converters
Microchip’s Delta-Sigma ADC families offer 16 to 24-bits of resolution with sampling rates from 4 sps to over 100 ksps. Product features include low power operation, low output noise and choices of I2C and SPI interfaces. High integration, including on-board voltage references and PGAs, and small packaging, such as SOT-23 and DFN, allow for high density solutions.

Successive Approximation Register (SAR) Analog-to-Digital Converters
Microchip's SAR (Successive Approximation Register) ADC offering provides a broad selection for low power applications. Based on advanced CMOS architecture and innovative design, these devices operate with an active conversion current as low as 175µA. The MCP30XX, MCP32XX, and MCP33XX families offer resolutions of 10-13-bits, sampling speeds of 22ksps to 200ksps, multiple channel inputs, and I2C or SPI interfaces.

Energy Measurement
Microchip’s Energy Measurement products enable accurate measurement of energy for electricity metering and power monitoring solutions. The MCP39xx devices offer high accuracy measurement while operating at low power. Some devices offer on-chip active power calculations while others simply offer high end A/D converters for high accuracy measurement with firmware available to perform the power calculations on any of Microchip’s PIC® microcontrollers.

Display Analog-to-Digital Converters
Microchip offers a wide variety of display ADCs, which provide a complete data acquisition system on a chip. The TC71XX devices can directly drive a LCD or LED display with 3½ and 4½ digit options making them ideal for multimeters and digital measurement devices.

Dual Slope Analog-to-Digital Converters
The TC5XX family of precision analog front ends implement a dual-slope architecture which provides 17-bit plus sign resolution. Noise rejection of 50/60Hz and flexible speed vs. resolution configuration make these devices suitable for a variety of data acquisition systems.

Binary and BCD Analog-to-Digital Converters
Microchip offers ADCs with BCD and binary outputs that are well-suited for direct display and microcontroller-based measurement systems. High precision plus industry standard interfaces and pinouts make these devices fit in applications such as sensor interfaces, process controls, panel meters, instrumentation.

Digital-to-Analog Converters
Microchip’s low cost D/A converter (DAC) product families feature low power operation down to 175µA with 8, 10 and 12-bit resolutions. I2C or SPI interface, non-volatile memory and internal voltage reference options are available. Non-volatile memory stores the DAC’s configuration during power down so that it is immediately available upon power up. Small form factor includes 6-pin SOT-23 packaging for single channel output and 10-pin MSOP for four channel outputs.

Digital Potentiometers
Microchip offers a wide variety of digital potentiometers that service a broad range of application needs.   These low power digital potentiometer families offers a wide range of solutions, in both volatile and non-volatile memory types, from 6 to 8 bits of resolution.  These products are offered in miniature packaging such as 6-pin SC-70 and 2mmx3mm DFN.

Frequency-to-Voltage / Voltage-to-Frequency
The TC9400/1/2 are low-cost frequency-to-voltage (F/V) converters utilizing low power CMOS technology. The converters accept a variable analog input signal and generate an output pulse train whose frequency is linearly proportional to the input voltage. The devices can also be used as highly-accurate frequency-to-voltage (F/V) converters, accepting virtually any input frequency waveform and providing a linearly-proportional voltage output.
