MCP3464T-E/ST - 16-Bit 153.6kSPS 4-Channel ADC | Microchip
MPN： MCP3464T-E/ST ✓ 啟用中MCP3464T-E/ST 概覽
A delta-sigma ADC is a voltage-to-digital converter category that uses oversampling, noise shaping, and digital filtering to obtain high effective resolution from a compact analog front end. Within the broader semiconductor hierarchy, the MCP3464 belongs to the ADC family, sits under data-converter ICs, and ultimately serves industrial measurement, instrumentation, and embedded-control applications. Its four-channel architecture supports simultaneous acquisition of multiple sensor outputs without requiring four separate converter packages.
The MCP3464T-E/ST combines 16-bit nominal resolution with programmable conversion rates up to 153.6 kSPS. The manufacturer describes the device as a low-noise converter with four differential or eight single-ended inputs, providing flexibility for bridge sensors, voltage inputs, and mixed measurement systems. Its SPI interface supports integration with microcontrollers and digital signal controllers while keeping conversion data and configuration controls on a compact serial bus.
The converter family includes related four-channel devices distinguished by integrated voltage-reference and packaging options. The manufacturer specifically identifies MCP3464R as the preferred pin-compatible choice for new designs because it includes an onboard voltage reference that is not present in MCP3464. This distinction is important when deciding whether the original MCP3464T-E/ST remains appropriate for a board under revision or whether a new design should adopt the referenced configuration.
The MCP3464T-E/ST is appropriate for industrial process monitoring, precision sensor acquisition, laboratory instrumentation, and embedded data acquisition. Its nominal 16-bit resolution suits measurements requiring more detail than an 8-bit or 12-bit converter, while the 153.6 kSPS maximum rate permits faster sampling than many low-speed high-resolution converters.
For a robust implementation, confirm the external reference requirements, analog input voltage range, digital interface levels, and selected output-data format against the manufacturer datasheet. The four-channel TSSOP footprint also requires a layout that separates sensitive analog inputs from SPI activity and provides suitable return paths for analog and digital return currents.
This product page combines the manufacturer product description, distributor identification, and package-level comparison data with practical selection guidance. It also distinguishes the original MCP3464T-E/ST from pin-compatible family members that add an onboard reference, helping engineers evaluate PCB reuse without overlooking functional changes.

典型應用
MCP3464T-E/ST 適用於 6 應用s: Industrial Process Monitoring, Precision Sensor Acquisition, Laboratory Instrumentation, Data Acquisition Modules, Condition Monitoring Systems, Automated Test Equipment.
Industrial Process Monitoring
The MCP3464T-E/ST suits multi-channel process monitoring where measurement accuracy and flexible input selection matter more than very high conversion speed. Its four differential channels can accept paired sensor signals and reject common-mode noise, while the single-ended configuration supports up to eight external signals. At 16-bit nominal resolution and up to 153.6 kSPS, the converter provides useful resolution for pressure, temperature, level, and current-loop measurements. The 20-pin TSSOP keeps the analog front end compact while the SPI interface limits digital wiring to a controller and peripheral devices. In a process-control board, use the differential inputs for bridge-based sensors, route analog and digital returns carefully, and verify the external reference configuration against the manufacturer electrical specifications.
Precision Sensor Acquisition
The MCP3464T-E/ST is appropriate for acquiring several precision sensor outputs in an embedded measurement system. Sixteen-bit resolution preserves fine amplitude detail, and the four differential inputs allow each sensor channel to use a dedicated signal pair. This arrangement is useful for strain, pressure, bridge, and other sensors whose useful signal occupies only part of the converter’s supported range. The delta-sigma architecture is particularly appropriate when the controller needs accurate results at moderate update rates rather than the very short latency associated with a high-speed flash ADC. Designers should check common-mode range and input protection, use a quiet reference arrangement, and ensure the SPI interface and digital return paths do not inject noise into the analog section.
Laboratory Instrumentation
The MCP3464T-E/ST can form the measurement front end of laboratory instruments that acquire several low-bandwidth analog quantities with high nominal resolution. Its 153.6 kSPS maximum rate gives sufficient throughput for many pressure, voltage, current, and resistance measurements, while the four-channel differential arrangement supports paired input instrumentation. The typical family signal-to-noise ratio of 97.3 dB, typical SFDR of 120 dB, and 16-bit ENOB indicate performance suited to precision bench equipment. For a laboratory instrument, define the reference source and analog front-end gain for the full expected input range, isolate SPI clocks from sensitive analog traces, and verify the selected data rate and digital filter configuration against the manufacturer timing documentation.
Data Acquisition Modules
The MCP3464T-E/ST works well as the core converter in a compact four-channel data-acquisition module. Eight single-ended inputs provide flexibility when each sensor has a grounded signal, while four differential inputs support channels that require paired sensing. Its 16-bit nominal resolution captures gradual changes in environmental, structural, and equipment-condition signals, and the 153.6 kSPS rate supports moderate-rate acquisition. The SPI interface allows the converter to operate with a compact embedded controller and simplifies the external connection compared with a parallel data bus. The design should include input protection appropriate to the measured sources, a stable reference arrangement, adequate analog filtering, and a pinout that keeps sensitive nets short and separated from clock and data traces.
Condition Monitoring Systems
The MCP3464T-E/ST can support condition-monitoring systems that compare multiple vibration, temperature, strain, or electrical signals over time. The multi-input architecture reduces the number of separate converter packages needed when several sensors must be acquired under similar timing conditions. Sixteen-bit resolution is useful for detecting small changes in slowly varying or filtered sensor signals, while the delta-sigma conversion method suits applications with low to moderate bandwidth. Use differential channels when sensor wiring introduces significant common-mode potential or ground offsets. Because monitoring systems often combine long sensor cables with sensitive analog circuitry, place protection and filtering at the connector, maintain controlled return paths, and test the reference and digital interface for noise coupling before deploying the module in service.
Automated Test Equipment
The MCP3464T-E/ST is applicable to automated test equipment that measures several low-speed analog parameters on a device under test. Four differential channels can support source-and-return measurements, while the eight single-ended arrangement can consolidate lower-cost probe channels. The 16-bit nominal resolution and up-to-153.6 kSPS rate provide a practical balance between measurement detail, conversion throughput, and circuit complexity. The SPI interface allows coordinated capture by a test controller and reduces pin count compared with a parallel ADC. In a production fixture, protect every external input, account for fixture offsets and settling time, and keep SPI activity away from high-impedance analog nodes. Confirm the allowable reference and input ranges before choosing input attenuation or gain stages.

設計說明
Separate analog inputs and reference routing from SPI clock, data, and digital return paths. Place input protection and filtering components close to the connector or sensor interface, and keep analog traces short and continuous. The four differential inputs should use paired routing where practical so that signal and return paths experience similar propagation conditions. Ground and decoupling connections should follow the reference layout in the manufacturer datasheet rather than relying on generic TSSOP placement rules.
Treat the SPI clock as a potentially fast switching source even though the ADC is intended for relatively low-bandwidth measurements. Route it away from sensitive input and reference nodes, use a continuous ground reference beneath the interface where practical, and place interface decoupling near the device power pins. Validate settling and conversion timing at the selected output-data rate because digital filtering and data latency settings affect when results can be sampled.
Confirm the external-reference configuration before committing the schematic because MCP3464R variants include an onboard voltage reference while MCP3464T-E/ST does not. Use a reference and supply arrangement whose noise, stability, and startup behavior meet the converter requirements. Do not assume that a package-compatible R variant can be substituted without reviewing the reference-related schematic and layout differences.
Do not select a replacement solely from the 20-pin TSSOP package. Check channel count, input configuration, reference availability, temperature grade, output data format, interface timing, and ordering suffix. The MCP3464R-E/ST is pin-compatible according to the manufacturer, but its onboard reference changes the circuit and layout review. Likewise, distinguish MCP3464-E/ST and MCP3464T-E/ST as separate ordering variants before approving a substitution.
