Output Voltage Range VOUT (Note 4) 2.1 — 12 V VOUT1 1x Mode 2.8 — 3 V Output Voltage VOUT2 2x Mode 5.2 — 6 V VOUT3 3x Mode (Note 5) 7.2 — 12 V IDD11 1x Mode, CPIEZO = No Load — 50 — µA Operating Current 1 IDD12 2x Mode, CPIEZO = No Load — 720 — µA IDD13 3x Mode, CPIEZO = No Load — 1,700 — µA IDD21 1x Mode, Single-ended application — 0.3 — mA Operating Current 2 IDD22 2x Mode, Single-ended application — 1.4 — mA IDD23 3x Mode, Single-ended application — 3.9 — mA IDD31 1x Mode, Differential application — 0.9 — mA Operating Current 3 IDD32 2x Mode, Differential application — 3.6 — mA IDD33 3x Mode, Differential application — 7.9 — mA Shutdown Current ISD DIN = 0V — — 1 µA Input Frequency fIN Rectangular pulse — 4 — kHz Oscillating Frequency fOSC — — 1 — MHz 1x Mode, From DIN signal High to 90% V t OUT ON1 — 270 — µs steady state 2x Mode, From DIN signal High to 90% V VOUT Start Delay Time t OUT ON2 — 320 — µs steady state 3x Mode From DIN signal High to 90% V t OUT ON3 — 350 — µs steady state Shutdown Delay Time tOFF DIN = H- > L — 42 — ms Output Short-Circuit Current ISC — — 40 — mA Control Terminal Voltage H VIH EN1, EN2, DIN pins 0.8*VIN — VIN V Control Terminal Voltage L VIL EN1, EN2, DIN pins 0 — 0.2*VIN V Control Terminal Current 1 IIH1 DIN = 3V — — 1 µA Control Terminal Current 2 IIH2 VEN1, VEN2 = 3V, DIN = 3V — — 1 µA Control Terminal Current 3 IIH3 VEN1, VEN2 = 3V, DIN = 0V — — 1 µA Notes: 4. It is possible to drive VOUT, VO1 and VO2 to 3x VDD. A supply voltage of 4V of more should not be used in 3x mode as this will exceed the maximum output voltage rating. 5. When designed under 3x mode, it should be carefully noted that the VOUT absolute maximum value should not exceed 15V. PAM8904 4 of 9 May 2017 Document number: DS37246 Rev. 2 - 2
