A | Page 4 of 20 Parameter Test Conditions/Comments B Version1 Unit POWER REQUIREMENTS VDD 2.7/5.25 V min/max IDD7, 8 During Conversion6 VDD = 4.75 V to 5.25 V 1.5 mA max VDD = 2.7 V to 3.6 V 1.2 mA max Normal Mode (Static) SCLK on or off 0.5 mA typ Normal Mode (Operational) VDD = 4.75 V to 5.25 V 0.7 mA max VDD= 2.7 V to 3.6 V 0.33 mA max Power-Down SCLK on or off 1 µA max Power Dissipation Normal Mode (Operational) VDD = 5 V 3 mW max VDD = 3 V 0.9 mW max Power-Down VDD = 5 V; SCLK on or off 5 µW max VDD = 3 V; SCLK on or off 3 µW max 1 Temperature range for B version: −40°C to +85°C. 2 See the section. Terminology 3 Analog inputs with slew rates exceeding 27 V/µs (full-scale input sine wave > 3.5 MHz) within the acquisition time may cause an incorrect result to be returned by the converter. 4 A dc input is applied to VIN– to provide a pseudo ground for VIN+. 5 The AD7457 is functional with a reference input range of 100 mV to VDD. 6 Guaranteed by characterization. 7 See the section. Power Consumption 8 Measured with a full-scale dc input. |
