Description

Product status link

LEOAD128

The LEOAD128 is a low power, multiplexed 8-input pure CMOS 12-bit analog-to-

digital converter specified for conversion from 50 ksps to 1 Msps. The architecture

is based on a successive-approximation register with internal track-and-hold. The

output serial data is straight binary and is compatible with SPI™.

The analog and digital power supplies operate from 2.7 V to 3.6 V, drawing a current

consumption of only 2 mA maximum.

The LEOAD128 can operate over a large temperature range of -40 °C to +125

°C and it is housed in plastic TSSOP-20, thin-shrink small outline package, 20

leads, using golden bonding and nickel/palladium/golden-lead-finishing to prevent

from whiskers.

The LEOAD128 is compliant with the ST-LEO-specification, dedicated specification

for space-ready rad-hard plastic products. This AEC-Q100-based specification offers

a specific trade-off among footprint size savings, cost of ownership and quality

assurance together with radiation hardness and large quantity capability.
