MCP3562T-E/ST - 24-Bit Dual-Channel ADC | Microchip
部品番号: MCP3562T-E/ST ✓ 生産中MCP3562T-E/ST 概要
A delta-sigma ADC is a class of analog-to-digital converter that uses oversampling, digital filtering, and noise shaping to obtain high resolution from a low-noise analog input. The MCP3562T-E/ST supports four single-ended or two differential channels, giving designers flexibility for measuring several unipolar sensors or two balanced bridges while retaining a compact 20-pin TSSOP footprint.
Key features include 24-bit resolution, programmable output data rates up to 153.6 kSPS, and four single-ended or two differential analog inputs. The converter architecture is designed for low-noise measurement rather than high-speed waveform capture, making it suitable for pressure, temperature, load-cell, current, and process-control signals. Its external-reference requirement should be considered carefully because the related MCP3562R includes an onboard voltage reference while MCP3562 does not.
The MCP3562 family uses a serial interface for configuration and data transfer. In a typical measurement circuit, analog signals pass through protection, filtering, and gain stages before entering the ADC inputs. Digital filtering then rejects out-of-band noise, while an external voltage reference establishes the conversion scale. This combination supports deterministic sensor measurements with relatively high effective resolution.
Typical uses include industrial process monitoring, portable instrumentation, environmental sensing, battery-powered measurement systems, and precision analog front ends. The TSSOP package also facilitates compact board layouts, although careful grounding, reference routing, and input filtering remain necessary to preserve the converter’s low-noise performance.
When designing a board around the MCP3562T-E/ST, verify the external reference voltage, digital supply levels, interface signals, and channel configuration against the manufacturer datasheet. Confirm that the selected data rate and digital filter settings provide enough conversion latency for the application. For new designs where an onboard reference simplifies the power tree, evaluate the manufacturer-recommended MCP3562R option and confirm its complete pin compatibility.
This page combines the manufacturer’s device information with practical selection guidance, application fit, and direct replacement considerations.

主な用途
MCP3562T-E/ST の用途: 6 件s: Industrial Process Measurement, Load-Cell and Bridge Sensor Acquisition, Environmental Monitoring, Portable Instrumentation, Precision Data Acquisition, Battery-Powered Sensor Nodes.
Industrial Process Measurement
The MCP3562T-E/ST is suitable for acquiring slow or medium-speed process variables from pressure, temperature, and level sensors. Its 24-bit resolution supports fine measurement granularity, while four single-ended inputs can reduce the number of converters required for a multichannel panel. With two differential inputs, the device can also monitor balanced bridge outputs from strain or pressure elements. At the maximum 153.6 kSPS data rate, it supports faster control loops than a slow-resolution converter, although actual loop bandwidth must remain within the digital-filter latency of the selected conversion mode. Use an accurate external reference because the MCP3562 does not include the onboard reference offered by MCP3562R.
おすすめ
Load-Cell and Bridge Sensor Acquisition
The two differential inputs of the MCP3562T-E/ST suit load cells, strain gauges, and other bridge-based sensors whose output is small and centered around a common reference potential. Differential conversion helps reject common-mode noise when the analog front end, grounding, and shielding are designed consistently. The 24-bit converter resolution is valuable for resolving small full-scale bridge voltages, while the maximum 153.6 kSPS rate permits faster sampling than many low-rate instrumentation ADCs. Because MCP3562 requires an external reference, the reference voltage and amplifier gain determine absolute scale accuracy. A low-noise reference and carefully placed input filtering are therefore central to achieving repeatable force or weight measurements.
おすすめ
Environmental Monitoring
The MCP3562T-E/ST can digitize multiple environmental sensor outputs in a compact monitoring node. Four single-ended channels allow connection of temperature, humidity, light, and gas sensors when their signal levels are compatible with the converter's input range. A differential configuration can support two balanced sensor pairs or circuits with a centered common-mode output. The 24-bit resolution preserves small changes that may be important in climate-control or air-quality systems, while programmable data rates let the designer balance throughput, filtering, and energy use. In a field-deployed node, protect the analog inputs from transients, keep the external reference quiet, and use averaged conversions or digital filtering when the application requires stable readings rather than maximum speed.
おすすめ
Portable Instrumentation
The 20-pin TSSOP package and low-noise delta-sigma architecture make the MCP3562T-E/ST appropriate for compact handheld measurement equipment. It can acquire several sensor channels without requiring a large flash-based ADC footprint, and the 24-bit resolution supports laboratory-style readings from low-level analog signals. Programmable conversion rates allow firmware to use slower, filtered measurements when battery energy is the priority and faster rates for transient or sampling applications. The external reference is a meaningful consideration in portable systems because it influences both accuracy and power budget. MCP3562R may simplify the reference design, but the final choice depends on the required reference accuracy, noise, and available power rails.
おすすめ
Precision Data Acquisition
The MCP3562T-E/ST is appropriate for precision data-acquisition systems that need more resolution than conventional 12-bit or 16-bit SAR converters. Four single-ended inputs provide a practical way to collect several slowly varying channels, and two differential inputs support noise-sensitive measurements where common-mode rejection is important. The delta-sigma conversion path and programmable output rate provide flexibility between resolution, bandwidth, and conversion latency. For laboratory or service equipment, average multiple readings, implement digital filtering appropriate to the selected data rate, and maintain a stable reference. The MCP3562R is worth evaluating when the onboard reference reduces circuit complexity, but verify every electrical limit and configuration sequence for the exact device suffix.
おすすめ
Battery-Powered Sensor Nodes
The MCP3562T-E/ST can serve as the measurement converter in a battery-powered sensor node that gathers multiple analog channels at controlled intervals. Its programmable data rate allows the system firmware to select a faster conversion mode during calibration or event capture and a slower mode for routine monitoring. Four single-ended inputs can reduce the number of separate converter packages, while differential operation can improve immunity to noise in remote sensor wiring. Energy use must be evaluated using the device's documented operating currents and shutdown behavior. The external reference also affects system-level power and accuracy, so compare the complete reference solution with MCP3562R before freezing the board design. Use low-leakage input protection and avoid unnecessary analog circuitry in duty-cycled nodes.

設計ノート
Follow the manufacturer layout guidance for the MCP3562 family and place the analog input, reference, and decoupling networks close to the associated pins. Keep the external reference return path short and avoid routing it beneath or beside digital clock and serial-interface traces. Use a continuous ground reference beneath the converter and analog section, with the return-current path chosen so switching currents do not share the sensitive measurement area.
Treat each analog input as a potentially low-level measurement node. Add input filtering appropriate to the selected output data rate, keep capacitor and leakage currents in mind, and provide protection that does not distort the required source impedance. For differential measurements, route each input as a balanced pair and maintain symmetrical geometry. The 24-bit nominal resolution should not be interpreted as guaranteed useful accuracy until the complete front end, reference, and digital filtering are evaluated.
The MCP3562T-E/ST requires an external voltage reference because the onboard reference is not included. Size the reference network for the required noise, temperature stability, startup, and load behavior specified by the manufacturer. Decouple the analog and digital supplies as directed in the datasheet, keep switching-regulator and high-current paths away from reference routing, and verify supply sequencing requirements. Compare the complete reference power and accuracy budget with MCP3562R when planning a new design.
