The MAX5823/MAX5824/MAX5825 8-channel, low-power, 8-/10-/12-bit, voltage-output digital-to-analog converters (DACs) include output buffers and an internal 3ppm/°C reference that is selectable to be 2.048V, 2.500V, or 4.096V. The MAX5823/MAX5824/MAX5825 accept a wide supply voltage range of 2.7V to 5.5V with extremely low power (6mW) consumption to accommodate most low-voltage applications. A precision external reference input allows rail-to-rail operation and presents a 100kΩ (typ) load to an external reference.
The MAX5823/MAX5824/MAX5825 have an I2C-compatible, 2-wire interface that operates at clock rates up to 400kHz. The DAC output is buffered and has a low supply current of less than 250µA per channel and a low offset error of ±0.5mV (typ). On power-up, the MAX5823/ MAX5824/MAX5825 reset the DAC outputs to zero or midscale based on the status of M/active-low Z logic input, providing flexibility for a variety of control applications. The internal reference is initially powered down to allow use of an external reference. The MAX5823/MAX5824/MAX5825 allow simultaneous output updates using software LOAD commands or the hardware load DAC logic input (active-low LDAC).
The MAX5823/MAX5824/MAX5825 feature a watchdog function which can be enabled to monitor the I/O interface for activity and integrity.
A clear logic input (active-low CLR) allows the contents of the CODE and the DAC registers to be cleared asynchronously and simultaneously sets the DAC outputs to the programmable default value. The MAX5823/MAX5824/MAX5825 are available in a 20-pin TSSOP and an ultra-small, 20-bump WLP package and are specified over the -40°C to +125°C temperature range.
Applications
- Automatic Tuning and Optical Control
- Gain and Offset Adjustment
- Portable Instrumentation
- Power Amplifier Control and Biasing
- Process Control and Servo Loops
- Programmable Voltage and Current Sources

MAXPMBAE
Maxim Analog Essentials Collection of Peripheral Modules
Product Detail
Maxim Analog Essentials is a collection of peripheral modules which can plug directly into any FPGA/CPU expansion port which follows the Pmod™ standard established by Digilent, Inc. The collection includes modules containing a wide variety of commonly used analog and mixed signal functions. The modules are supported by software which includes FPGA configuration files for three popular FPGA platforms: Avnet LX-9, Digilent Nexys 3 and Avnet ZEDBoard, as well as example programs to exercise and demonstrate each module. While the example programs demonstrate the module’s functionality, they are well partitioned and documented allowing the core routines to be easily cut and pasted into your own programs. The combination of plug-in simplicity and easy software integration allows for quick migration from idea to working prototype.
