MCP3564-E/ST - 24-Bit 153.6kSPS ADC | Microchip
MPN: MCP3564-E/ST ✓ Hoạt độngMCP3564-E/ST Tóm tắt
A delta-sigma ADC is a type of analog-to-digital converter that uses oversampling, noise shaping, and digital filtering to convert continuous analog voltages into high-resolution digital codes. Within the data-converter hierarchy, it belongs to the ADC/DAC category and provides an alternative to successive-approximation and flash converters when low-noise integration and programmable output data rates are more important than very low conversion latency.
The verified product information identifies a 24-bit conversion resolution, a maximum output rate of 153.6 ksps, and eight single-ended or four differential input channels. The low-noise architecture is useful when measuring sensor outputs, process-control signals, or low-amplitude analog quantities where the ADC must preserve signal detail while converting it into a digital representation. Its 20-lead TSSOP package supports conventional surface-mount PCB assembly.
The MCP3564 is one member of the MCP3561/2/4 family, which provides a common platform for two-, four-, and eight-channel low-noise 24-bit delta-sigma converter applications. Programmable data-rate capability allows the interface timing to be matched to different measurement bandwidths. This can reduce unnecessary digital data transfer in systems where the source changes slowly, while faster rates remain available for dynamic measurements.
Typical uses include industrial process monitoring, precision instrumentation, environmental sensing, factory data acquisition, and embedded measurement systems. Eight single-ended channels are useful for monitoring several sensors with a common ground reference, while four differential channels help reject common-mode noise when the source is balanced or when the analog front end can drive differential signals.
Designers should account for the absence of an onboard reference in the MCP3564 and provide an appropriate external voltage reference. Input filtering, source settling, grounding, and PCB layout should preserve the low-noise performance of the converter. The exact electrical limits, reference requirements, interface details, and recommended external circuitry must be verified in the manufacturer datasheet before production design.
This product record combines verified manufacturer and distributor information with a structured comparison against the pin-compatible MCP3564R-E/ST. It also highlights selection trade-offs, pricing context, and practical design considerations that help engineers distinguish the standard MCP3564 from the reference-equipped MCP3564R without relying on undocumented assumptions.

Ứng dụng tiêu biểu

Industrial Process Monitoring
The MCP3564-E/ST fits industrial process monitoring because it combines 24-bit resolution with eight single-ended or four differential channels and a maximum conversion rate of 153.6 ksps. It can acquire several low-level sensor signals through a common analog front end, while differential operation reduces common-mode pickup when required by the transmitter. The delta-sigma architecture is especially useful for slow process variables such as pressure, temperature, or level. Designers should verify the electrical limits, reference implementation, digital interface, and filtering requirements in the manufacturer datasheet before deployment.
Được đề xuất
Precision Environmental Sensing
The MCP3564-E/ST is appropriate for multichannel environmental monitoring where gas, humidity, temperature, or light sensors produce low-amplitude analog signals. Its 24-bit resolution preserves fine amplitude detail, and the eight-single-ended-channel configuration can reduce the number of separate converter packages required by a monitoring board. Differential inputs provide an alternative when sensor circuitry can develop a balanced signal. External-reference accuracy and source noise remain important, so the final signal chain should be evaluated against the verified 153.6 ksps maximum data rate rather than treating that rate as mandatory for every channel.
Được đề xuất
Factory Data Acquisition
MCP3564-E/ST can serve as the central analog acquisition device in factory test and data-acquisition equipment. Its 24-bit conversion resolution supports precise characterization of slow sensor and actuator signals, while eight single-ended inputs allow one device to monitor multiple channels. Four differential modes support balanced industrial interfaces and can improve rejection of noise coupled into both signal conductors. System partitioning should account for channel settling, anti-alias filtering, external-reference performance, and the serial-data interface defined by the manufacturer datasheet.
Được đề xuất
Medical and Laboratory Instrumentation
The low-noise 24-bit MCP3564-E/ST can be evaluated for laboratory and medical-instrument signal acquisition when channel count and resolution meet the measurement architecture. Eight single-ended inputs support compact multi-sensor instrumentation, while four differential inputs suit front ends that generate balanced signals to reduce interference. The device is a signal-conversion component rather than a complete medical signal chain, so input protection, isolation, reference accuracy, electrode-interface design, and regulatory validation remain system-level responsibilities. Verify electrical and environmental limits from the manufacturer documentation before clinical or diagnostic use.
Được đề xuất
Embedded Sensor Interface
MCP3564-E/ST fits embedded systems that need high-resolution conversion from several analog sensor outputs. The 20-lead TSSOP package can simplify board assembly, and programmable conversion-rate selection can help match acquisition bandwidth to the physical behavior of temperature, pressure, or position sensors. Using fewer channels can reduce software overhead and unnecessary data volume. The design must provide an external reference, confirm input range and common-mode limits, and implement the documented digital protocol so that the MCU or controller can retrieve and process each conversion result correctly.
Được đề xuất
Precision Test and Measurement
The MCP3564-E/ST is useful in precision test and measurement systems that convert low-level analog outputs into high-resolution digital data. Four differential channels can acquire balanced outputs from sensors or instrumentation, while eight single-ended channels support a broader set of test points. The 24-bit resolution provides a high numerical scale for calibration and analysis, and the 153.6 ksps maximum rate provides flexibility for signals with different bandwidth requirements. Source impedance, reference stability, input filtering, digital timing, and the manufacturer's recommended layout should be verified to preserve measurement performance.

Ghi chú thiết kế
The MCP3564 does not include the onboard voltage reference present in MCP3564R, so the external reference implementation is part of the power and accuracy design. Select the reference from the manufacturer's specified electrical characteristics rather than inferring a voltage from the preferred MCP3564R variant. Check reference noise, drift, startup behavior, and bypass requirements against the required conversion accuracy and the operating-temperature range stated in the datasheet.
Keep the analog input paths and external reference connections compact and away from high-current or fast-switching traces. Follow the manufacturer layout and grounding recommendations, including the placement and return path of decoupling components. Differential channels should be routed as balanced pairs where practical, and input sources should be checked for settling behavior before the converter's selected data rate is finalized.
The 24-bit resolution makes reference and front-end noise relevant even when the converter's maximum rate of 153.6 ksps is not used. Apply the manufacturer's recommended anti-alias filtering, provide a low-noise reference, and ensure sensor or amplifier output noise does not dominate the acquisition chain. Validate noise, common-mode rejection, and channel-to-channel isolation in the final board because the supplied web results do not include numeric values for those parameters.
Do not treat MCP3564R-E/ST as an exact functional duplicate: although it is pin compatible and preferred for new designs, it adds an onboard voltage reference. Verify whether an existing MCP3564 board supplies a usable external reference and whether that reference should be removed or isolated. Also confirm the required channel mode, data rate, digital interface, and package orientation from the manufacturer documentation before ordering or substituting the part.
