11 / 67 page  DS992F2 11 CS53L30 3 Characteristics and Specifications Table 3-6. MIC BIAS Characteristics Test conditions (unless otherwise specified): Fig. 2-1 shows CS53L30 connections; GNDA = GNDD = 0; all voltages are with respect to ground; VA = 1.8 V, VP = 3.6 V, TA = +25°C; only one bias output is powered up at a time; MCLK_INT_SCALE = 0. Parameters Min Typ Max Units Output voltage 1 1.The output voltage includes attenuation due to the MIC BIAS output resistance (ROUT). MIC_BIAS_CTRL = 01 (1.8-V mode) MIC_BIAS_CTRL = 10 (2.7-V mode) 1.71 2.61 1.80 2.75 1.89 2.86 V V Mic bias startup delay 2 2.Startup delay times are approximate and vary with MCLKINT frequency. If MCLK_INT_SCALE = 1, the startup delay time is scaled up by the MCLKINT scaling factor. The MCLKINT scaling factor is 1, 2, or 4, depending on FsEXT. See Table 4-2. —10— ms Rise time 3 3.From 10% to 90% of typical output voltage. External capacitor on MICx_BIAS is as shown in Fig. 2-1. IOUT = 500 µA, MIC_BIAS_CTRL = 01 (1.8-V mode) IOUT = 500 µA, MIC_BIAS_CTRL = 10 (2.7-V mode) IOUT = 2 mA — — — 0.2 0.5 — — — 3 ms ms ms DC output current (IOUT) Per output — — 2 mA Integrated output noise f = 100 Hz–20 kHz — 3 — µVrms Dropout voltage 4 4.Dropout voltage indicates the point where an output’s voltage starts to vary significantly with reductions to its supply voltage. When the VP supply voltage drops below the programmed MICx_BIAS output voltage plus the dropout voltage, the MICx_BIAS output voltage progressively decreases as its supply decreases. Dropout voltage is measured by reducing the VP supply until MICx_BIAS drops 10 mV from its initial voltage with the default typical test condition VP voltage (= 3.6 V, as in test conditions listed above). The difference between the VP supply voltage and the MICx_BIAS voltage at this point is the dropout voltage. For instance, if the initial MICx_BIAS output is 2.86 V when VP = 3.6 V and VP = 3.19 V when MICx_BIAS drops to 2.85 V (–10 mV), the dropout voltage is 340 mV (3.19 V – 2.85 V). — — 340 mV PSRR reduction voltage 5 5.PSRR voltage indicates the point where an output’s supply PSRR starts to degrade significantly with supply voltage reductions. When the VP supply voltage drops below the programmed MICx_BIAS output voltage plus the PSRR reduction voltage, the MICx_BIAS output’s PSRR progressively decreases as its supply decreases. PSRR reduction voltage is measured by reducing the VP supply until MICx_BIAS PSRR @ 217 Hz falls below 100 dB. The difference between the VP supply voltage and the MICx_BIAS voltage at this point is the PSRR reduction voltage. For instance, if the MICx_BIAS PSRR falls to 99.9 dB when VP is reduced to 3.25 V and the MICx_BIAS output voltage is 2.75 V at that point, PSRR reduction voltage is 500 mV (3.25 V – 2.75 V). — — 500 mV Output resistance (ROUT) IOUT = 2-mA — 30 — Table 3-7.
