12-BIT 500KSPS ADC

BW1251X

GENERAL DESCRIPTION

FEATURES

• Resolution : 12-bit

The BW1251X is a CMOS 3.3V 12-bit analog-to-

digital converter (ADC). It converts the analog input

signal into 12-bit binary digital codes at a maximum

conversion rate of 500KSPS with 2.5MHz clock.

The device is a recycling type monolithic ADC with

an on-chip sample-and-hold function. The ADC has

power down mode.

• Maximum Conversion Rate : 500KSPS

• Main Clock : 2.5MHz

• Power Supply : 3.3V ±0.3V

• Total Current : 20uA (Standby Mode)

2.2mA (Normal Operation)

• Input Range : 0.0V ~ 3.3V (3.3V_P-P)

• Differential Linearity Error : ±0.7 LSB

• Integral Linearity Error : ±0.8 LSB

• Signal to Noise & Distortion Ratio : 70dB

• Digital Output : CMOS Level

TYPICAL APPLICATIONS

• Operating Temperature Range : 0 °C ~ 70 °C
