This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTE: 1. θJA is measured with the component mounted on an evaluation PC board in free air. Electrical Specifications TA = 25 oC, V+ = 5V, Zero Pot Centered, Gain Pot = 2.4kΩ, Unless Otherwise Specified PARAMETER TEST CONDITIONS MIN TYP MAX UNITS Operating Supply Voltage Range, V+ 4.5 5 5.5 V Supply Current, I+ 100k Ω to V+ on Pins 3, 4, 5 - - 17 mA Input Impedance, ZI - 100 - M Ω Input Bias Current, IIB Pins 10 and 11 - -80 - nA Unadjusted Zero Offset V11-V10 = 0V, Read Decoded Output -12 - +12 mV Unadjusted Gain V11-V10 = 900mV, Read Decoded Output 846 - 954 mV Linearity Notes 1 and 2 -1 - +1 Count Conversion Rate Slow Mode Pin 6 = Open or GND - 4 - Hz Fast Mode Pin 6 = 5V - 96 - Hz Conversion Control Voltage (Hold Mode) at Pin 6 0.8 1.2 1.6 V Common Mode Input Voltage Range, VICR Notes 3, 4 -0.2 - +0.2 V BCD Sink Current at Pins 1, 2, 15, 16 VBCD ≥ 0.5V, at Logic Zero State 0.4 1.6 - mA Digit Select Sink Current at Pins 3, 4, 5 VDIGIT Select = 4V at Logic Zero State 1.6 2.5 - mA Zero Temperature Coefficient VI = 0V, Zero Pot Centered - 10 - µV/oV Gain Temperature Coefficient VI = 900mV, Gain Pot = 2.4kΩ - 0.005 - %/oC NOTES: 1. Apply 0V across V11 to V10. Adjust zero potentiometer to give 000mV reading. Apply 900mV to input and adjust gain potentiometer to give 900mV reading. 2. Linearity is measured as a difference from a straight line drawn through zero and positive full scale. Limits do not include ±0.5 count bit digitizing error. 3. For applications where low input pin 10 is not operated at pin 7 potential, a return path of not more than 100k Ω resistance must be provided for input bias currents. 4. The common mode input voltage above ground cannot exceed +0.2V if the full input signal range of 999mV is required at pin 11. That is, pin 11 may not operate higher than 1.2V positive with respect to ground or 0.2V negative with respect to ground. If the maximum input signal is less than 999mV, the common mode input voltage may be raised accordingly. CA3162, CA3162A |
