Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
Low-power serial ADC runs up to 200Ksample/s
New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
Analogue inputs control input current limit, charge current, and voltage.
An integrated 3.3V LDO supplies over 20mA current to any external circuitry or ICs, such as a keyboard controller.
Three monitoring outputs simplify design, and save external component cost and board space.
Two analogue outputs are available for charge current and input current; a digital output is used to detect AC-adapter presence.
The MAX8730 provides 0.5% accurate battery-voltage regulation, which increases battery capacity and minimises charging time.
The device can be hardwired or controlled by a microprocessor to set the charging current or voltage.
Based on the presence or absence of an AC adapter, the MAX8730 uses two P-channel MOSFETs to automatically select the appropriate source for powering the system.
The MAX8730 features AC-adapter current limiting.
The IC monitors the current drawn from the adapter and adjusts the charge current so that supplying the system load and the charger simultaneously does not overload the adapter.
This important feature enables system operation with lower cost AC adapters.
The MAX8730 is packaged in a space-saving 28-pin QFN (5 x 5mm), and is specified for the extended industrial temperature range (-40 to +85C).
The MAX8730 is also available in a lead-free package.
Prices start at $5.04 (1000-up, FOB USA).
