NIPPON PRECISION CIRCUITS—8

Serial input timing (

BCKI, LRCI, DI/INF2N, IW1N/DIL, IW2N/DIR)

VSS = VSSAC = 0 V, Ta = −40 to 85 °C

1. CKSLN = HIGH (192fs), V DD = V DDAC = 4.75 to 5.25 V, Ta = −40 to 70 °C

2. CKSLN = LOW (256fs), V DD = V DDAC = 4.50 to 5.25 V

CKSLN = HIGH (192fs), V DD = V DDAC = 3.00 to 4.75 V

3. CKSLN = LOW (256fs), V DD = V DDAC = 3.00 to 4.50 V
