Notes (refer to Figure 4 for definitions):
1. ICP-DN vs ICP-UP = charge pump output current up vs down mismatch = [|E| – |B|]/[ 1/2 * {|E| + |B|}] * 100%.
2. ICP vs VCP = charge pump output current magnitude variation vs voltage = [ 1/2 * {|F| – |D|}]/[1/2 * {|F| +|D|}] * 100% and
[1/2 * {|A| - |C|}]/[1/2 *{|A| + |C|}] * 100%.
3. ICP vs TA = charge pump output current magnitude variation vs. temperature = [|E @ temp| – |E @ 25 °C|]/|E @ 25 °C| * 100% and [|B @
temp| – |B @ 25 °C|]/|B @ 25°C| * 100%.
