概要
Description
AD7904BRUZ-REEL is an Analog Devices part: a four-channel, 12-bit successive-approximation ADC designed for data acquisition and instrumentation. It multiplexes four analog inputs and converts them to digital data that can be read by a microcontroller or DSP via a common interface. The BRUZ suffix denotes the package style, while REEL indicates tape-and-reel packaging for automated assembly. Typical uses include instrumentation, industrial controls, automotive, and telemetry where multiple sensors need digitizing in a compact, low-power device. For exact electrical specs (sampling rate, input range, reference options, power, temperature range) refer to the AD7904 datasheet and packaging documentation.
Equivalent
Equivalent parts to AD7904BRUZ-REEL (12-bit, ~1 MSPS ADC) include Microchip MCP3201, MCP3202, MCP3204, and MCP3208. All are 12-bit, 1 MSPS ADCs with SPI interfaces. For similar performance, check other vendors’ 12-bit/1-MSPS devices (TI, Analog Devices) and use cross-references to verify pinouts and voltage ranges.
Features
I don’t have the exact datasheet in memory, but here are the typical features you can expect for the AD7904 family and the BRUZ-REEL packaging:
- High-resolution SAR ADC architecture
- 14/12-bit class resolution (depends on exact part revision) with accurate conversion
- Serial interface (SPI-compatible) for microcontroller integration
- Differential or single-ended input configurations
- Internal/external reference options (reference input with buffering)
- Wide supply range with low-power modes and possible power-down
- Analog input common-mode and signal range suitable for mid-supply operation
- On-chip sample-and-hold / fast acquisition capability
- Industrial/TEMPERATURE range options (depending on grade)
- Packaging: multiple-lead options (surface-mount) with tape-and-reel (REEL) packaging for automated assembly
- Typical precision features: low distortion, low noise, good linearity guarantees
