MCP3562R-E/ST - 24-Bit 153.6kSPS ADC | Microchip Technology
MPN： MCP3562R-E/ST ✓ 啟用中MCP3562R-E/ST 概覽
A delta-sigma ADC is a type of analog-to-digital converter that uses continuous-time oversampling, digital filtering, and noise shaping to convert analog voltages into high-resolution digital codes. Positioned within the ADC, data converter, and semiconductor hierarchy, this component is intended for sensors, instrumentation, and control systems that require more than 16-bit measurement resolution in a relatively compact package.
The MCP3562R supports 24-bit resolution, four single-ended inputs or two differential inputs, and programmable conversion rates reaching 153.6 kSPS. Its integrated internal voltage reference reduces the need for an external reference circuit, while the dual differential-input capability supports common-mode rejection when measuring small signals. The manufacturer identifies the R suffix as the preferred pin-compatible option for new designs.
Two principal implementation details distinguish the device within Microchip's ADC portfolio. First, its integrated reference supports a more self-contained analog measurement design than the MCP3562 version, which does not include the onboard reference. Second, the same 20-pin TSSOP footprint allows board-oriented designs to compare the MCP3562R with closely related family members rather than immediately requiring a new land pattern.
Typical uses include industrial process monitoring, precision sensor acquisition, laboratory instrumentation, and embedded measurement systems. Two differential channels are useful for bridge or current-sense measurements when common-mode noise must be rejected, while four single-ended channels can support multiple sensors sharing one converter. The maximum 153.6 kSPS data rate also supports faster sampled measurements than conventional slow-resolution sigma-delta converters.
For a new design, treat the R version as the preferred family member because it combines pin compatibility with an internal voltage reference. Confirm the exact input-range, reference, supply, digital-interface, and timing limits in the manufacturer datasheet before finalizing analog front-end values. Use a common ground plane, place input filtering close to the converter, and account for acquisition settling when changing input channels.
This product summary connects the manufacturer's core specifications with package, application, and comparison guidance. It also identifies the practical distinction between the integrated-reference R variant and the non-reference MCP3562, helping designers select the correct member of the pin-compatible Microchip family without changing the basic converter architecture.

典型應用
MCP3562R-E/ST 適用於 6 應用s: Precision Industrial Sensor Acquisition, Bridge and Current-Shunt Measurement, Laboratory Measurement Instrumentation, Environmental Monitoring Systems, Embedded Process Control, Portable Measurement Devices.
Precision Industrial Sensor Acquisition
The MCP3562R-E/ST fits industrial sensor acquisition systems that need higher resolution than ordinary 16-bit converters and can operate from a 3 V supply. Its four single-ended inputs allow several grounded or single-ended sensors to share one conversion engine, while two differential inputs support measurements where common-mode noise must be rejected. The programmable rate reaches 153.6 kSPS for faster process monitoring, and the internal reference reduces the number of external reference components. Engineers should confirm the required input range and configure the digital filter according to the manufacturer’s recommended circuit.
Bridge and Current-Shunt Measurement
The MCP3562R-E/ST is appropriate for differential bridge, shunt, and instrumentation-amplifier outputs because it can convert two differential channels at 24-bit nominal resolution. Differential operation helps suppress common-mode voltage present on industrial wiring, while the maximum 153.6 kSPS rate provides flexibility for fast control loops or dynamic measurements. The integrated voltage reference simplifies the reference section of new designs. Input common-mode limits, differential range, and settling behavior must be checked against the datasheet before connecting external transducers.
Laboratory Measurement Instrumentation
For laboratory instruments, the MCP3562R-E/ST combines a 24-bit delta-sigma conversion core, programmable data rate up to 153.6 kSPS, and selectable single-ended or differential input arrangements in a compact 20-pin TSSOP. These characteristics support precision measurement front ends where multiple transducers must be digitized through a common converter. The integrated reference is particularly useful when reducing analog complexity is important. Layout should prioritize low-noise grounding, short analog traces, and separation from clocks or switching nodes to preserve the converter’s intended performance.
Environmental Monitoring Systems
Environmental monitoring systems can use the MCP3562R-E/ST to digitize outputs from multiple low-bandwidth sensors such as temperature, pressure, humidity, or gas-sensor analog front ends. Four single-ended channels reduce converter count when each sensor shares a common ground, while the 24-bit nominal resolution preserves fine changes in slowly varying signals. Programmable conversion rates allow the system to trade throughput against filtering and noise performance. Select the rate and digital-filter settings that match the sensor bandwidth rather than operating continuously at the 153.6 kSPS maximum.
Embedded Process Control
The MCP3562R-E/ST suits embedded process-control loops that require more measurement resolution than a 16-bit converter but do not need to support every input range offered by a wider family member. Two differential channels can monitor current and voltage in a power stage, and the programmable rate supports sampling through 153.6 kSPS. The 3 V operating supply and internal reference help simplify compact control boards. Firmware must allow the required settling time after channel selection, and analog traces should be routed away from high-current switching paths.
Portable Measurement Devices
Portable instruments benefit from the MCP3562R-E/ST because its 24-bit conversion capability, internal reference, and compact TSSOP-20 package can reduce component count and board area. The four single-ended inputs support compact multi-sensor products, and the differential mode is useful when the sensor includes its own signal conditioning. At a 3 V supply, power-conscious designs can still select a lower conversion rate when the measurement bandwidth is modest. Battery and grounding design must prevent digital activity and charger switching from degrading the low-noise analog result.

主要差異化特點
- Integrated reference in the preferred family member (對比MCP3562-E/ST)

- Matches the 153.6 kSPS rate and 24-bit resolution class (對比MCP3464R-E/ST)
設計說明
Route analog input traces away from SPI clock, chip-select, and switching-node traces. Keep the input filter close to the MCP3562R-E/ST pins, use a continuous ground reference beneath the analog section, and place bypass capacitors at the supply pins. Because this converter supports rates up to 153.6 kSPS, layout-induced coupling can affect the usable result even when the nominal resolution is 24 bit.
Design the 3 V supply path so it remains quiet during conversion. Use short connections and local decoupling at the device, and separate analog return currents from digital output currents where the board architecture allows. Do not assume that the nominal 24-bit resolution guarantees equivalent noise performance at every data rate; choose the conversion rate and digital-filter configuration to balance throughput, settling, and noise requirements.
Do not substitute the MCP3562-E/ST without accounting for its lack of an onboard voltage reference. Also avoid assuming that all related 20-pin TSSOP devices have identical pin functions, differential-input limits, or acquisition timing. Before a drop-in substitution, compare the manufacturer pin table, input range, common-mode limits, reference circuit, digital interface, and conversion settling requirements for every affected channel.
