MCP3462T-E/ST - 16-Bit Dual Delta-Sigma ADC | Microchip
MPN: MCP3462T-E/ST ✓ ActiveMCP3462T-E/ST Overview
A delta-sigma ADC is a category of data-conversion IC that uses continuous-time oversampling and digital filtering to convert an analog input into a high-resolution digital value. Its application hierarchy is ADC → data-converter IC → analog-to-digital converter → signal-chain semiconductor. Delta-sigma converters are especially useful when a system needs good resolution, flexible conversion rates, and digital filtering without requiring a very high-speed flash or successive-approximation converter.
The MCP3462T-E/ST combines a 16-bit conversion format with four single-ended or two differential inputs in a single dual-converter arrangement. Differential operation helps reject common-mode noise when paired with suitable input circuitry, while single-ended operation supports simpler sensor and voltage-measurement channels. Its selectable data rate supports acquisition architectures that trade conversion speed for output filtering and noise performance.
The serial interface includes SPI, allowing the ADC to communicate with a microcontroller, digital signal controller, or other embedded processor. The manufacturer datasheet describes a programmable data rate, internal oscillator, and integrated temperature sensor. These resources can simplify system design by reducing the number of external timing and sensing components needed for a compact measurement channel.
Typical uses include industrial process monitoring, precision sensor acquisition, laboratory instrumentation, medical equipment, and embedded data loggers. The MCP3462T-E/ST is especially appropriate when two analog channels must be digitized with 16-bit resolution and 153.6 kSPS maximum throughput. Differential pairs can be used for bridge sensors or small-signal transducers where signal integrity is important.
PCB implementation should follow the manufacturer pin-description table and recommended decoupling layout. Keep analog and digital return currents separated, place input and reference components close to their associated pins, and use a quiet ground strategy around the converter. The SPI traces should be length-matched where practical and kept away from high-current switching nodes to minimize conversion errors.

Typical Applications
MCP3462T-E/ST is suitable for 6 applications: Industrial Process Monitoring, Precision Sensor Acquisition, Medical Monitoring Equipment, Laboratory Instrumentation, Environmental Sensor Logging, Battery-Powered Measurement.
Industrial Process Monitoring
The MCP3462T-E/ST fits industrial process-monitoring systems that need to digitize several slowly changing or medium-bandwidth sensor outputs. Its 16-bit resolution and four single-ended or two differential inputs allow two analog channels to share one converter, while the 153.6 kSPS maximum rate supports synchronized acquisition at a useful balance of throughput and filtering. The -40°C to +125°C operating range suits equipment deployed across industrial environments. Place the converter near the analog input network, use the differential arrangement when sensors produce small signals riding on common-mode voltage, and route the SPI bus away from switching power stages.
Recommended
Precision Sensor Acquisition
The MCP3462T-E/ST is appropriate for precision sensor front ends requiring more resolution than a basic 8-bit or 12-bit acquisition channel. Two differential input pairs can be used for bridge, strain-gauge, or low-level transducer signals, with the differential configuration helping suppress common-mode interference. Its 16-bit conversion format preserves fine amplitude detail, and the selectable rate up to 153.6 kSPS accommodates sensor bandwidths ranging from slow temperature measurements to faster dynamic signals. The internal oscillator and temperature sensor reduce external support circuitry, while SPI provides a straightforward connection to a digital controller.
Recommended
Medical Monitoring Equipment
The MCP3462T-E/ST can serve as the acquisition front end in medical monitoring equipment when the design requires two high-resolution analog channels. Differential inputs are useful for low-amplitude physiological or diagnostic signals because they help reject common-mode noise coupled into long sensor connections. The 16-bit resolution supports fine signal discrimination, and the maximum 153.6 kSPS rate provides flexibility for waveform and physiological-band acquisitions. The -40°C to +125°C rating supports industrial ambient conditions around compact medical equipment. Layout must prioritize input shielding, clean analog grounding, and isolation from motors, relays, and display converters.
Recommended
Laboratory Instrumentation
The MCP3462T-E/ST fits laboratory instruments that acquire two analog channels through a compact serial interface. Its 16-bit delta-sigma architecture, internal oscillator, and integrated temperature sensor can support measurement channels in programmable instruments, data loggers, and bench-top monitoring systems. A maximum rate of 153.6 kSPS allows the designer to select a conversion rate appropriate for the signal bandwidth instead of operating every channel at the maximum speed. The 20-pin TSSOP package supports compact board layouts, and SPI simplifies integration with a microcontroller. For highest accuracy, follow the manufacturer reference-network and grounding guidance.
Recommended
Environmental Sensor Logging
The MCP3462T-E/ST is well suited to environmental data loggers that combine multiple low-bandwidth sensor channels with an embedded controller. Four single-ended inputs can measure resistive sensors or external analog conditions, while two differential inputs support grounded or floating transducers. The 16-bit format can retain small variations in slow environmental signals, and the selectable data rate up to 153.6 kSPS provides flexibility for periodic or continuous sampling. Its integrated temperature sensor offers an additional local measurement function, while the internal oscillator can simplify clocking. Select a lower rate when longer conversion intervals are acceptable to reduce switching and processing activity.
Recommended
Battery-Powered Measurement
The MCP3462T-E/ST can support compact, battery-powered measurement systems where analog resolution, channel count, and board area are important. Two conversion channels and the selectable data rate up to 153.6 kSPS allow designers to match conversion activity to the workload instead of continuously running at the highest rate. The 3 V operating option is compatible with common low-voltage power rails, and the 20-pin TSSOP package limits board footprint. Internal oscillator and temperature-sensor resources can reduce external component count. The overall power budget should still be checked against the selected data rate and digital interface activity using the manufacturer electrical characteristics.

Design Notes
Follow the manufacturer datasheet's recommended decoupling and analog-layout arrangement. Place input, reference, and bypass components directly beside their associated pins, keep the analog return path continuous, and separate SPI return current from sensitive input nodes. Because the converter supports differential operation, route each differential pair with consistent geometry and terminate them according to the selected source impedance.
Treat analog inputs as precision signal paths rather than general-purpose logic nets. Keep traces away from switching-regulator outputs, relay contacts, high-current motor traces, and fast digital clock edges. Use a quiet ground region around the converter, establish a clear analog-to-digital return boundary, and verify the installed reference network against the manufacturer recommendations for the chosen data rate.
Do not assume that every MCP346x family member is interchangeable merely because the family uses similar 20-pin TSSOP packaging. Compare channel count, analog-pin assignment, differential-pair routing, supply limits, SPI timing, configuration registers, and conversion timing against the MCP3462T-E/ST before approving a substitution. Firmware should also verify the expected conversion-data status and scaling rather than relying only on the nominal 16-bit word width.
Select the conversion rate and digital-interface activity together with the analog-supply requirements in the manufacturer electrical characteristics. A lower data rate can reduce conversion activity in periodic acquisition systems, while a faster setting may improve temporal resolution. Validate the power-supply topology, reference startup behavior, and decoupling capacitance against the manufacturer application guidance rather than relying on generic values.
