5 / 29 page ADC08060 www.ti.com SNAS120H – OCTOBER 2000 – REVISED MARCH 2013 Converter Electrical Characteristics The following specifications apply for VA = DR VD = +3.0VDC, VRT = +1.9V, VRB = 0.3V, CL = 10 pF, fCLK = 60 MHz at 50% duty cycle. Boldface limits apply for TJ = TMIN to TMAX: all other limits TA = 25°C (1) (2) (3) Units Symbol Parameter Conditions Typical (4) Limits (4) (Limits) DC ACCURACY INL Integral Non-Linearity ±0.5 ±1.3 LSB (max) +1.0 LSB (max) DNL Differential Non-Linearity ±0.4 −0.9 LSB (min) Missing Codes 0 (max) FSE Full Scale Error 18 ±28 mV (max) ZSE Zero Scale Offset Error 26 ±35 mV (max) ANALOG INPUT AND REFERENCE CHARACTERISTICS VRB V (min) VIN Input Voltage 1.6 VRT V (max) (CLK LOW) 3 pF CIN VIN Input Capacitance VIN = 0.75V +0.5 Vrms (CLK HIGH) 4 pF RIN RIN Input Resistance >1 M Ω BW Full Power Bandwidth 200 MHz VA V (max) VRT Top Reference Voltage 1.9 1.0 V (min) VRT − 1.0 V (max) VRB Bottom Reference Voltage 0.3 0 V (min) 1.0 V (min) VRT - VRB Reference Delta 1.6 2.3 V (max) 150 Ω (min) RREF Reference Ladder Resistance VRT to VRB 220 300 Ω (max) 5.3 mA (min) IREF Reference Ladder Current 7.3 10.6 mA (max) (1) The Electrical characteristics tables list ensured specifications under the listed Recommended Conditions except as otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations for room temperature only and are not ensured. (2) The analog inputs are protected as shown below. Input voltage magnitudes up to VA + 300 mV or to 300 mV below GND will not damage this device. However, errors in the A/D conversion can occur if the input goes above DR VD or below GND by more than 100 mV. For example, if VA is 2.7VDC the full-scale input voltage must be ≤2.6VDC to ensure accurate conversions. (3) To ensure accuracy, it is required that VA and DR VD be well bypassed. Each supply pin must be decoupled with separate bypass capacitors. (4) Typical figures are at TJ = 25°C, and represent most likely parametric norms at specific conditions at the time of product characterization and are not ensured. Test limits are specified to TI's AOQL (Average Outgoing Quality Level). Copyright © 2000–2013, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: ADC08060 |
