1 1 ACTAR meeting – Santiago March 2008 Requirements Features required not available in standard ASICs for HEP: Auto-triggerable. Large dynamic range. Low noise. Multiple sampling ? : –For tracks with angles. –For common mode rejection Hess2, jv 2008

2 2 ACTAR meeting – Santiago March 2008 ALTRO For: The most advanced chip including A/D conversion On chip Baseline correction. Digital zero supression. External PA Against: Power 35mW/ch 16 ch./chips only. External PA. PASA treats only « cathod » signal polarity. Baseline correction limited.
