MIC7122 DS20006290A-page 6 2020 Microchip Technology Inc. DC ELECTRICAL CHARACTERISTICS (15V) VV+ = +15V, VV– = 0V, VCM = 1.5V, VOUT = VV+/2; RL = 1 MΩ; TJ = +25°C; Note 1. Parameters Sym. Min. Typ. Max. Units Conditions Input Offset Voltage VOS — 0.5 9 mV — Input Offset Voltage Average Drift TCVOS — 3.0 — μV/°C — Input Bias Current IB — 1.0 10 pA — — 64 500 –40°C ≤ TJ ≤ +85°C Input Offset Current IOS — 0.5 5 pA — — 32 250 –40°C ≤ TJ ≤ +85°C Input Resistance RIN — >1 — TΩ — Common-Mode Rejection Ratio CMRR 60 85 — dB –0.3V ≤ VCM ≤ 15.3V, Note 2 Power Supply Rejection Ratio PSRR 55 100 — dB VV+ = |VV–| = 2.5V to 7.5V, VOUT = VCM = 0 Large Signal Voltage Gain AV — 340 — V/mV Sourcing or sinking, RL = 2 kΩ, Note 3 — 300 — Sourcing or sinking, RL = 600Ω, Note 3 Common-Mode Input Capacitance CIN — 3 — pF — Note 1: All limits guaranteed by testing or statistical analysis. 2: CMRR is determined as follows: The maximum ΔVOS over the VCM range is divided by the magnitude of the VCM range. The measurement points are: VCM = VV– – 0.3V, (VV+ – VV–)/2, and VV+ + 0.3V. 3: RL connected to 7.5V. Sourcing: 7.5V ≤ VOUT ≤ 12.5V. Sinking: 2.5V ≤ VOUT ≤ 7.5V. 4: Continuous short circuit may exceed absolute maximum TJ under some conditions. |
