LDOs handle automotive extremes
Designed for harsh automotive environments, the MAX15006 and MAX15007 can operate from a cold-crank voltage as low as 4V and withstand load-dump transients as high as 45V.
New from Maxim Integrated Products are the MAX15006 and MAX15007 ultra-low-quiescent-current high-voltage low-dropout (LDO) linear regulators Designed for harsh automotive environments, the MAX15006 and MAX15007 can operate from a cold-crank voltage as low as 4V and withstand load-dump transients as high as 45V

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.
Both devices deliver up to 50mA of output current and have an ultralow 10uA (typical) quiescent current at no load.
An internal P-channel pass transistor keeps the quiescent current as low as 90uA (typical), even with a 50mA load.
Additionally, the MAX15007 consumes only 3uA of quiescent current in shutdown.
The ultra-low-quiescent-current of these devices makes them ideal for use in battery-operated systems and "always-on" automotive applications, such as remote keyless entry (RKE), receiver modules for tire pressure monitoring, and power-supply modules for "keep-alive" circuits.
The MAX15006 and MAX15007 include robust short-circuit protection.
The output of each regulator can be shorted to ground for an indefinite duration, even with an input voltage as high as 40V.
In addition, both devices include thermal shutdown to protect the devices from excessive temperatures at the die.
The MAX15006 and MAX15007 are specified for operation over the -40 to +125C automotive temperature range and are available in 3.3 or 5V output versions.
These devices are packaged in a 3 x 3mm, thermally enhanced 6-pin TDFN or a thermally enhanced 8-pin SO that are capable of dissipating 1.9 and 1.86W, respectively, at an ambient temperature of +70C.
Prices start at US $0.50 (1000-up, FOB USA).
