DS18B20U 描述
NOTES: 1. All VDD pins must be connected to 3.3V power supply. 2. All VDDQ pins must be connected to appropriate power supply: 3.3V if OPT pin for that port is set to VIH (3.3V), and 2.5V if OPT pin for that port is set to VIL (0V) 3. All VSS pins must be connected to ground. 4. Package body is approximately 15mm x 15mm x 1.4mm with 0.8mm ball pitch. 5. This package code is used to reference the package diagram. 6. This text does not indicate orientation of the actual part-marking.
DS18B20U 特点
The DS18B20U supports 24-bit linear PCM output data, with sampling frequencies up to 216kHz. The DS18B20U can also be configured to output either 64x or 128x oversampled, 1-bit direct stream digital (DSD) data for each channel. In addition, the DS18B20U supports a DSD input mode, allowing 1-bit DSD to 24-bit PCM data format conversion utilizing the on-chip digital decimation filter. These features make the DS18B20U suitable for a variety of digital audio recording and processing applications. The DS18B20U includes a flexible audio serial port inter- face, which supports standard PCM audio data formats, as well as time division multiplexed (TDM) PCM data formats. Multiple format support allows the system designer to choose the interface format that best suits the end applica- tion. Audio data format selection, sampling mode configu- ration, and high-pass filter functions are all programmed using dedicated control pins.
DS18B20U 应用
The DS18B20U/934/935/936 is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the DS18B20U/934/935/936 in order to reduce component count, board space, and system cost.
