141 / 152 page  ST72C171 141/152 9.13 OP-AMP Module Characteristics These op-amp specific values take precedence over any generic values given elsewhere in the docu- ment. (T =25oC, V DD - V SS = 5 V ). 1) AVCL = Closed loop gain (repeater configuration) 2) Tested with positve input connected to internal band gap (reference voltage enabled) and negative in- put floating. 3) Data based on characterization, not tested in production 4) Data guaranteed by design, not tested in production 5) Slew rate is the rate of change from 10% to 90% of the output voltage step. SPGA1 / SPGA2 - Software Programmable Gain Operational Amplifiers Symbol Parameter Condition Min Typ Max Unit |Vio| Input Offset Voltage 3 10 mV ICC Supply Current per amplifier 2) VDD=5.0V, AVCL=1, no load1) 0.8 2 mA CMR 3) Common Mode Rejection Ratio 70 dB SVR 3) Supply Voltage Rejection Ratio 70 dB Avd 3) Voltage Gain (RL=1KΩ) 100 V/mV VOH High Level Ouput Voltage (RL=10KΩ) VDD=5V 4.9 V VOL Low Level Ouput Voltage (RL=10KΩ) VDD=5V 0.10 V ISC 3) Short circuit Current Sourced Short circuit Current Sunk Vo= 5V connected to VSS Vo= 0V connected to VDD 45 70 mA mA GPB Gain Bandwidth Product 4 MHz SR+ Slew Rate 5) AVCL=1 1) 1V/ µs SR- Slew Rate 5) AVCL=1 1) 1V/ µs en 3) Thermal Noise 50 Φm 3) Phase margin 40 55 Degrees Cin 4) Input Capacitance 10 pF Vicm 4) Common Mode Input Voltage Range VSS- 0.2 VDD +0.2 V ∆VRef Reference Voltage (VDDA/8 step) Precision ±10 % ∆V BG Band Gap Precision ±10 % ∆Gain Programmable Gain Precision ±10 % nV Hz 1 – |
