5 / 14 page  www.austriamicrosystems.com Revision 1.01 5 - 14 AS1500 Data Sheet - El ectrical Characte ristics AS1502 / AS1503 – SPECIFICATIONS VCC = 3V±10% or 5V±10%, VA = VCC, VB = 0V, –40ºC ≤ TA ≤ +125ºC unless otherwise noted. PDISS Power Dissipation (CMOS) 8 VIH = VCC or VIL = 0V, VCC = 5.5V 27.5 µW PSSR Power Supply Suppression Ratio VCC = 5V+0.5VP sine wave @ 1kHz AS1500, Version: 10k Ω -54 -25 dB AS1501, Version: 20k Ω -52 -25 dB Dynamic Characteristics 9 BW_10k Bandwidth –3dB Bandwidth –3dB RWB = 10kΩ, VCC = 5V 1000 kHz BW_20k RWB = 20kΩ, VCC = 5V 500 kHz THDW Total Harmonic Distortion VA = 1VRMS + 2VDC, VB = 2VDC, f = 1kHz 0.003 % tS_10k VW Settling Time RWB = 5kΩ, VA = VCC, VB = 0V, ±1% Error Band 2 µs tS_20k RWB = 10kΩ, VA = VCC, VB = 0V, ±1% Error Band 4µs eNWB_10k Resistor Noise Voltage RWB = 5kΩ, f =1kHz 9nV/ √ Hz eNWB_20k RWB = 10kΩ, f =1kHz 13 nV/ √ Hz 1. Typicals represent average readings at 25ºC and VCC = 5V. 2. Wiper is not connected. IAB = 350µA for the 10kΩ version and 175µA for the 20kΩ version. 3. All Tempcos are guaranteed by design and not subject to production test. 4. Terminal A is not connected. IW = 350µA for the 10kΩ version and 175µA for the 20kΩ version. 5. Resistor terminals A, B, W have no limitations on polarity with respect to each other. 6. All capacitances are guaranteed by design and not subject to production test. Resistor-terminal capacitance tests are measured with 2.5V bias on the measured terminal. The remaining resistor terminals are left open cir- cuit. 7. Worst-case supply current consumed when input logic level at 2.4V, standard characteristic of CMOS logic. 8. PDISS is calculated from (IDD×VCC). CMOS logic level inputs result in minimum power dissipation. 9. All dynamic characteristics are guaranteed by design and not subject to production test. All dynamic characteris- tics use VCC=5V.
