ADC08L060
8-Bit, 10 MSPS to 60 MSPS, 0.65 mW/MSPS A/D
Converter with Internal Sample-and-Hold
General Description
The ADC08L060 is a low-power, 8-bit, monolithic analog-to-
digital converter with an on-chip track-and-hold circuit. Opti-
mized for low cost, low power, small size and ease of use,
this product operates at conversion rates of 10 MSPS to
60 MSPS while consuming just 0.65 mW per MHz of clock
frequency, or 39 mW at 60 MSPS. Raising the PD pin puts
the ADC08L060 into a Power Down mode where it con-
sumes < 1.0 mW.
The unique architecture achieves 7.6 Effective Bits. The
ADC08L060 is resistant to latch-up and the outputs are
short-circuit proof. The top and bottom of the ADC08L060’s
reference ladder are available for connections, enabling a
wide range of input possibilities. The digital outputs are
TTL/CMOS compatible with a separate output power supply
pin to support interfacing with 1.8V to 3V logic. The digital
inputs (CLK and PD) are TTL/CMOS compatible.
The ADC08L060 is offered in a 24-lead plastic package
(TSSOP) and is specified over the industrial temperature
range of −40˚C to +85˚C.

Converter Electrical Characteristics (Continued)
The following specifications apply for VA = VDR = +3.0VDC, VRT = +1.9V, VRB = 0.3V, CL = 10 pF, fCLK = 60 MHz at 50% duty
cycle. Boldface limits apply for TA = TMIN to TMAX: all other limits TA = 25˚C (Notes 7, 8)

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: All voltages are measured with respect to GND = AGND = DR GND = 0V, unless otherwise specified.
Note 3: When the input voltage at any pin exceeds the power supplies (that is, less than AGND or DR GND, or greater than VA or VDR), the current at that pin should
be limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of
25 mA to two.
Note 4: The absolute maximum junction temperature (TJmax) for this device is 150˚C. The maximum allowable power dissipation is dictated by TJmax, the
junction-to-ambient thermal resistance (θJA), and the ambient temperature (TA), and can be calculated using the formula PDMAX = (TJmax − TA) / θJA. In the 24-pin
TSSOP, θJA is 92˚C/W, so PDMAX = 1,358 mW at 25˚C and 706 mW at the maximum operating ambient temperature of 85˚C. Note that the power consumption of
this device under normal operation will typically be about 49 mW (40 mW quiescent power + 4 mW reference ladder power + 5 mW to drive the output bus
capacitance). The values for maximum power dissipation listed above will be reached only when the ADC08L060 is operated in a severe fault condition (e.g., when
input or output pins are driven beyond the power supply voltages, or the power supply polarity is reversed). Obviously, such conditions should always be avoided.
Note 5: Human body model is 100 pF capacitor discharged through a 1.5 kresistor. Machine model is 220 pF discharged through ZERO Ohms.
Note 6: See AN-450, “Surface Mounting Methods and Their Effect on Product Reliability”.
Note 7: 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 VDR or below GND by more than 100 mV. For example, if VA is 2.7VDC the full-scale input
voltage must be 2.8VDC to ensure accurate conversions.

Note 8: To guarantee accuracy, it is required that VA and VDR be well bypassed. Each supply pin must be decoupled with separate bypass capacitors.
Note 9: Typical figures are at TJ = 25˚C, and represent most likely parametric norms. Test limits are guaranteed to National’s AOQL (Average Outgoing Quality
Level).
Note 10: IDR is the current consumed by the switching of the output drivers and is primarily determined by the load capacitance on the output pins, the supply
voltage, VDR, and the rate at which the outputs are switching (which is signal dependent), IDR = VDR (CO x fO + C1 x f1 + … + C71 x f7) where VDR is the output
driver power supply voltage, Cn is the total capacitance on any given output pin, and fn is the average frequency at which that pin is toggling.
