isppac20 Lattice Semiconductor Corp., isppac20 Datasheet - Page 3

• Manufacturer Part Number: isppac20
• Description: In-system Programmable Analog Circuit
• Manufacturer: Lattice Semiconductor Corp.

Notes: (1) A wider input range of 0.7V to 4.3V is typical, but not guaranteed. Inputs larger than this will be clipped. Input signals are also subject
to common-mode voltage limitations. Refer to the table of conditions in this datasheet. (2) Refer to theory of operation section later in this datasheet
for explanation of differential voltage swing computation. (3) To insure full spec performance an additional auto-calibration should be performed
after initial turn-on and the device reaches thermal stability.(4) The user-provided voltage on this pin (CMV
programming) alternative to the default 2.5V VREF
