10-BIT 250KSPS SAR ADC

ADC1255X

FEATURES

GENERAL DESCRIPTION

The ADC1255X is a CMOS 10-bit low supply, low

power, successive approximation A/D converter which is

composed of auto-zeroing comparator, 10-bit DAC, clock

generator, successive approximation register(SAR) and

output register. The 10-bit DAC consists of capacitor

arrays and resistor strings. The conversion result can be

· Resolution: 10-Bit

· Differential Linearity Error:±1.0 LSB(Max)

· Integral Linearity Error:±2.0 LSB(Typ)

· Maximum Conversion Rate: 250KSPS

· Low Power Consumption: 2.2mW(Typ)

· Power Supply Voltage: 1.8V(Typ)

· No Pipeline Delays

accessed over

parallel interface. The ADC1255X

operates with a single +1.8V power supply and the

conversion rate is up to 250KSPS.

· No Missing Code Guaranteed

· Operation Temperature Range: 0º C~70º C
