Product details
Overview
ADMW1001BCPZ from Analog Devices is a highly flexible, firmware-upgradeable condition monitoring IC that integrates sensor excitation, 24-bit Σ-Δ ADC conversion, embedded linearization (for PT100/1000 RTDs and J/K/T thermocouples), 50/60 Hz antialiasing rejection, and SPI/I²C sensor interfacing - enabling direct digitization of compensated temperature, bridge, and custom sensors in industrial asset health systems.
For engineers reviewing the ADMW1001BCPZ datasheet, ADMW1001BCPZ pinout, ADMW1001BCPZ application, or ADMW1001BCPZ equivalent, this page delivers verified technical context, real-world measurement channel configurations, confirmed diagnostic capabilities (open-wire, short-circuit, LUT validation), exact SPI master/slave timing parameters, and validated alternatives for condition monitoring node design.
Technical Context
The ADMW1001BCPZ implements dual independent 24-bit Σ-Δ ADCs with programmable gain (1–128), integrated PGA, on-chip FIFO, and per-channel sequencer logic - supporting simultaneous 50 Hz and 60 Hz notch filtering at 8.24 Hz output rate. It features two universal analog input channels (CH1/CH2) configurable for RTD, 4-/6-wire bridge, or ratiometric referencing, plus two dedicated thermocouple inputs (CH1_TC+/IEXC, CH2_TC+/IEXC) sharing COM_TC− and requiring TC_BIAS biasing.
Its digital architecture includes dual SPI interfaces (slave mode for host communication via CS0/MOSI0/MISO0/SCLK0; master mode for sensor control via CS1/MOSI1/MISO1/SCLK1), I²C sensor interface (SDA/SCL), GPIOs (GPIO0–GPIO2), and diagnostics engine with open-wire detection, short-circuit monitoring, and lookup table integrity checks - all managed by field-upgradable firmware within the MeasureWare ecosystem.

FAQ
What sensor types does the ADMW1001BCPZ natively support without external firmware updates?
The ADMW1001BCPZ firmware revision 1.0 natively supports compensated J-, K-, and T-type thermocouples, 2-/3-wire PT100 and PT1000 RTDs, 4-wire Wheatstone bridges, and custom sensors via user-defined lookup tables. It also interfaces directly with I²C and SPI sensors through dedicated ports. All supported sensor types are handled with on-chip linearization and compensation - no host-side computation is required for basic operation of ADMW1001BCPZ.
How does the ADMW1001BCPZ achieve simultaneous 50 Hz and 60 Hz antialiasing rejection?
The ADMW1001BCPZ achieves simultaneous 50 Hz and 60 Hz antialiasing rejection through a digitally implemented notch filter synchronized to its Σ-Δ modulator clock. At an output data rate of 8.24 Hz, the device provides 97 dB rejection for both frequencies with gain = 1. This capability is hard-coded in the ADC's digital filter path and requires no external components - ensuring robust performance in electrically noisy industrial environments where ADMW1001BCPZ is deployed.
Can the ADMW1001BCPZ operate with an external reference, and what are the input requirements?
Yes, the ADMW1001BCPZ supports external reference inputs via VREF+ and VREF− pins. In buffered mode, the input range is AGND + 0.1 V to AVDD − 0.1 V; in unbuffered mode, the minimum differential voltage must be ≥400 mV. Input current is ≤27 nA (buffered) or ≤500 nA/V (unbuffered). External reference use maintains full 24-bit performance but requires careful layout to preserve noise immunity - a key consideration when designing precision measurement circuits with ADMW1001BCPZ.
What is the role of the TC_BIAS pin in thermocouple measurements with the ADMW1001BCPZ?
The TC_BIAS pin on the ADMW1001BCPZ provides a mid-supply bias voltage used to level-shift the COM_TC− pin during thermocouple measurements. Because thermocouple outputs are bipolar relative to AGND, TC_BIAS ensures the input stays within the ADC's common-mode range. It must be connected directly to COM_TC− when measuring thermocouples on CH1_TC+/IEXC or CH2_TC+/IEXC - failure to do so causes measurement saturation or clipping. This biasing scheme is mandatory for correct ADMW1001BCPZ thermocouple operation.
Does the ADMW1001BCPZ require pre-flashing with firmware before first use?
Yes, the ADMW1001BCPZ ships with only a firmware loader - not functional measurement firmware. To enable sensor support (RTD, thermocouple, bridge), users must flash the latest ADMW1001BCPZ firmware using Analog Devices' custom flash loader toolset. Firmware revisions are available on the ADMW1001 product page and MeasureWare Studio. Without flashing, the ADMW1001BCPZ remains non-operational - this step is essential before any measurement functionality can be accessed.
