The minimum and maximum limits are expanded for the ATE to account for an ambient range from 22°C to 32°C with a 4-µA/°C temperature coefficient on the supply current. INPUT Common-mode input range, low TA ≈ 25°C, CMRR > 92 dB VS– – 0.2 VS– – 0 V A TA = –40°C to 125°C, CMRR > 92 dB VS– – 0 B Common-mode input range, high TA ≈ 25°C, CMRR > 92 dB VS+ – 1.3 VS+ – 1.2 V A TA = –40°C to 125°C, CMRR > 92 dB VS+ – 1.3 B CMRR Common-mode rejection ratio 95 105 dB A Input impedance common-mode 100 || 1.3 kΩ || pF C Input impedance differential mode 50 || 0.8 kΩ || pF C OUTPUT VOL Output voltage, low TA ≈ 25°C, G = 6 VS– + 0.05 VS– + 0.1 V A TA = –40°C to 125°C, G = 6 B VOH Output voltage, high TA ≈ 25°C, G = 6 VS+ – 0.1 VS+ – 0.05 V A TA = –40°C to 125°C, G = 6 B Maximum current into a resistive load TA ≈ 25°C, ±1.53 V into 41.3 Ω, VIO < 2 mV ±35 ±40 mA A Linear current into a resistive load TA ≈ 25°C, ±1.81 V into 70.6 Ω, AOL > 80 dB ±25 ±28 mA A TA = –40°C to 125°C, ±1.58 V into 70.6 Ω, AOL > 80 dB ±22 ±25 B DC output impedance G = 6 0.02 Ω C POWER SUPPLY Specified operating voltage 2.7 5 5.4 V B Quiescent operating current TA ≈ 25°C (6) 913 960 993 µA A TA = –40°C to 125°C 700 960 1330 B dIq/dT Quiescent current temperature coefficient TA = –40°C to 125°C 2.6 3 3.4 µA/°C B +PSRR Positive power-supply rejection ratio 98 110 dB A –PSRR Negative power-supply rejection ratio 93 105 dB A POWER DOWN (Pin Must be Driven, SOT23-6 and SC70-6) Enable voltage threshold Specified on above VS–+ 1.5 V 1.5 V A Disable voltage threshold Specified off below VS–+ 0.55 V 0.55 V A Disable pin bias current PD = VS– to VS+ –50 20 50 nA A Power-down quiescent current PD = 0.55 V 2 5 µA A Turnon time delay Time from PD = high to VOUT = 90% of final value 1.7 usec C Turnoff time delay Time from PD = low to VOUT = 10% of original value 100 ns C |
