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.
The step-up DC/DC regulator, featuring undervoltage lockout (UVLO), soft-start, and internal current limits, provides the regulated supply voltage for the panel source-driver ICs.
The convertor is a high-frequency (640kHz/1.2MHz) current-mode regulator with an integrated 14V N-channel power MOSFET that allows the use of ultrasmall inductors and ceramic capacitors.
The current-mode control architecture provides fast transient response to pulsed loads.
The regulator achieves efficiencies over 90% by bootstrapping the supply rail of the internal gate driver from the step-up regulator output.
The fully integrated, programmable, switch control block helps reduce flickers on the screen.
The integrated high-current operational amplifier is designed to drive the LCD backplane (VCOM).
The amplifier features high output current (+/-150mA), fast slew rate (7.5V/us), wide bandwidth (12MHz), and rail-to-rail inputs and outputs.
The MAX8758 is available in a 4 x 4mm, 24-pin, TQFN package with a 0.8mm maximum thickness for ultrathin LCD panels.
The device operates over the -40 to +85C temperature range.
Prices start at $3.30 (1000-up, FOB USA).
A pre-assembled MAX8758 evaluation kit is available with recommended external components to reduce design time.
