Description

The WM8152SCDS/R is a 16-bit analogue front end/digitiser IC which processes and digitises the analogue output signals from CCD sensors or Contact Image Sensors (CIS) at pixel sample rates of up to 12MSPS. The features of WM8152SCDS/R are: (1)16-bit ADC; (2)12MSPS conversion rate; (3)Low power - 225mW typical; (4)5V single supply or 5V/3.3V dual supply operation; (5)Single channel operation; (6)Correlated double sampling; (7)Programmable gain (8-bit resolution); (8)Programmable offset adjust (8-bit resolution); (9)Programmable clamp voltage; (10)4-bit wide multiplexed data output format.

The following is about the absolute maximum ratings of WM8152SCDS/R: (1)Analogue supply voltage: AVDD GND - 0.3V to GND + 7V; (2)Digital core voltage: DVDD1 GND - 0.3V to GND + 7V; (3)Digital IO supply voltage: DVDD2 GND - 0.3V to GND + 7V; (4)Digital ground: DGND GND - 0.3V to GND + 0.3V; (5)Analogue grounds: AGND1 . 2 GND - 0.3V to GND + 0.3V; (6)Operating temperature range: 0°C +70°C; (7)Storage temperature after soldering: -65°C +150°C; (8)Package body temperature (soldering, 10 seconds): +260°C; (9)Package body temperature (soldering, 2 minutes): +183°C.

The electrical characteristics of the WM8152SCDS/R are: (1)Full-scale input voltage range: 0.30Vp-p typ at Max Gain; (2)Input signal limits: 0 min and VDD V max; (3)Full-scale transition error: -50mV min, 10 mV typ and +50 mV max at Gain = 0dB; PGA[7:0] = 07(hex); (4)Zero-scale transition error: -50mV min, 10 mV typ and +50 mV max at  Gain = 0dB; (5)Differential non-linearity: 1.25 LSB; (6)Integral non-linearity: 25 LSB; (7)Total output noise: 4.5 LSB rms at Min Gain.
