Intersil HI1-565ASD-2 High speed, monolithic d/a converter with reference Datasheet

HI-565A
Data Sheet
High Speed, Monolithic D/A Converter
with Reference
The HI-565A is a fast, 12-bit, current output, digital-to-analog
converter. The monolithic chip includes a precision voltage
reference, thin-film R2R ladder, reference control amplifier
and twelve high speed bipolar current switches.
The Intersil dielectric isolation process provides latch free
operation while minimizing stray capacitance and leakage
currents, to produce an excellent combination of speed and
accuracy. Also, ground currents are minimized to produce a
low and constant current through the ground terminal, which
reduces error due to code dependent ground currents.
HI-565A dice are laser trimmed for a maximum integral
nonlinearity error of ±0.5 LSB at 25oC. In addition, the low
noise buried zener reference is trimmed both for absolute
value and temperature coefficient. Power dissipation is
typically 250mW, with ±15V supplies.
The HI-565A is offered in both commercial and military
grades. See Ordering Information.

Nonlinearity of a D/A converter is an important measure of
its accuracy. It describes the deviation from an ideal straight
line transfer curve drawn between zero (all bits OFF) and full
scale (all bits ON) (End Point Method).
Differential Nonlinearity for a D/A converter, it is the
difference between the actual output voltage change and the
ideal (1 LSB) voltage change for a one bit change in code. A
Differential Nonlinearity of ±1 LSB or less guarantees
monotonicity; i.e., the output always increases for an
increasing input.
Settling Time is the time required for the output to settle to
within the specified error band for any input code transition.
It is usually specified for a full scale or major carry transition,
settling to within ±0.5 LSB of final value.
Gain Drift is the change in full scale analog output over the
specified temperature range, expressed in parts per million
of full scale range per oC (ppm of FSR/ oC). Gain error is
measured with respect to 25oC at high (TH) and low (TL)
temperatures. Gain drift is calculated for both high (TH
-25oC) and low ranges (25oC -TL) by dividing the gain error
by the respective change in temperature. The specification is
the larger of the two representing worst-case drift.
Offset Drift is the change in analog output with all bits OFF
over the specified temperature range expressed in parts per
million of full scale range per oC (ppm of FSR/ oC). Offset
error is measured with respect to 25oC at high (TH) and low
(TL) temperatures. Offset Drift is calculated for both high (TH
-25oC) and low (25oC -TL) ranges by dividing the offset error
by the respective change in temperature. The specification
given is the larger of the two, representing worst-case drift.
4
Power Supply Sensitivity is a measure of the change in
gain and offset of the D/A converter resulting from a change
in -15V or +15V supplies. It is specified under DC conditions
and expressed as parts per million of full scale range per
percent of change in power supply (ppm of FSR/%).
Compliance Voltage is the maximum output voltage range
that can be tolerated and still maintain its specified accuracy.
Compliance Limit implies functional operation only, and
makes no claims to accuracy.
Glitch a glitch on the output of a D/A converter is a transient
spike resulting from unequal internal ON-OFF switching
times. Worst case glitches usually occur at half-scale or the
major carry code transition from 011...1 to 100...0 or vice
versa. For example, if turn ON is greater than turn OFF for
011...1 to 100...0, an intermediate state of 000...0 exists,
such that, the output momentarily glitches toward zero
output. Matched switching times and fast switching will
reduce glitches considerably.
Detailed Description
Op Amp Selection
The Hl-565As current output may be converted to voltage
using the standard connections shown in Figures 1 and 2.
The choice of operational amplifier should be reviewed for
each application, since a significant trade-off may be made
between speed and accuracy.
For highest precision, use an HA-5130. This amplifier
contributes negligible error, but requires about 11µs to settle
within ±0.1% following a 10V step.
The Intersil HA-2600 is the best all-around choice for this
application, and it settles in 1.5µs (also to ±0.1% following a
10V step). Remember, settling time for the DAC amplifier
combination is the square root of tD2 plus tA2, where tD, tA
are settling times for the DAC and amplifier.
No-Trim Operation
The Hl-565A will perform as specified without calibration
adjustments. To operate without calibration, substitute 50Ω
resistors for the 100Ω trimming potentiometers: In Figure 1
replace R2 with 50Ω also remove the network on pin 8 and
connect 50Ω to ground. For bipolar operation in Figure 2,
replace R3 and R4 with 50Ω resistors.
With these changes, performance is guaranteed as shown
under Specifications, “External Adjustments”. Typical unipolar
zero will be ±0.5 LSB plus the op amp offset.
The feedback capacitor, C, must be selected to minimize
settling time.
Calibration
Calibration provides the maximum accuracy from a
converter by adjusting its gain and offset errors to zero. For
the Hl-565A, these adjustments are similar whether the
current output is used, or whether an external op amp is
HI-565A
added to convert this current to a voltage. Refer to Table 2
for the voltage output case, along with Figure 1 or Figure 2.
Next adjust positive FS. This is a gain error adjustment, which
rotates the output characteristic about the negative FS value.
Calibration is a two step process for each of the five output
ranges shown in Table 2. First adjust the negative full scale
(zero for unipolar ranges). This is an offset adjust which
translates the output characteristic, i.e., affects each code by
the same amount.
For the bipolar ranges, this approach leaves an error at the
zero code, whose maximum value is the same as for integral
nonlinearity error. In general, only two values of output may
be calibrated exactly; all others must tolerate some error.
Choosing the extreme end points (plus and minus full scale)
minimizes this distributed error for all other codes.

Settling Time
This is a challenging measurement, in which the result
depends on the method chosen, the precision and quality of
test equipment and the operating configuration of the DAC
(test conditions). As a result, the different techniques in use
by converter manufacturers can lead to consistently different
results. An engineer should understand the advantage and
limitations of a given test method before using the specified
settling time as a basis for design.
The previous approach calls for a strobed comparator to
sense final perturbations of the DAC output waveform. This
gives the LSB a reasonable magnitude (814µV for the
HI-565A), which provides the comparator with enough
overdrive to establish an accurate ±0.5 LSB window about the
final settled value. Also, the required test conditions simulate
the DACs environment for a common application - use in a
successive approximation A/D converter. Considerable
experience has shown this to be a reliable and repeatable way
to measure settling time.
The usual specification is based on a 10V step, produced by
simultaneously switching all bits from off-to-on (tON) or onto-off (tOFF). The slower of the two cases is specified, as
measured from 50% of the digital input transition to the final
entry within a window of ±0.5 LSB about the settled value.
Four measurements characterize a given type of DAC:
(a)
tON , to final value +0.5 LSB
(b)
tON , to final value -0.5 LSB
(c) tOFF, to final value +0.5 LSB
(d)
tOFF, to final value -0.5 LSB
6
(Cases (b) and (c) may be eliminated unless the overshoot
exceeds 0.5 LSB). For example, refer to Figure 3 for the
measurement of case (d).
Procedure
As shown in Figure 3B, settling time equals tX plus the
comparator delay (tD = 15ns). To measure tX :
• Adjust the delay on generator No. 2 for a tX of several
microseconds. This assures that the DAC output has
settled to its final value.
• Switch on the LSB (+5V).
• Adjust the VLSB supply for 50% triggering at
COMPARATOR OUT. This is indicated by traces of
equal brightness on the oscilloscope display as shown
in Figure 3B. Note DVM reading.
• Switch the LSB to Pulse (P).
• Readjust the VLSB supply for 50% triggering as before,
and note DVM reading. One LSB equals one tenth the
difference in the DVM readings noted above.
• Adjust the VLSB supply to reduce the DVM reading by 5
LSBs (DVM reads 10X, so this sets the comparator to
sense the final settled value minus 0.5 LSB).
Comparator output disappears.
• Reduce generator No. 2 delay until comparator output
reappears, and adjust for “equal brightness”.
• Measure tX from scope as shown in Figure 3B. Settling
time equals tX + tD, i.e., tX + 15ns.

Other Considerations
Grounds
Bypass Capacitors
The Hl-565A has two ground terminals, pin 5 (REF GND)
and pin 12 (PWR GND). These should not be tied together
near the package unless that point is also the system signal
ground to which all returns are connected. (If such a point
exists, then separate paths are required to pins 5 and 12).
Power supply bypass capacitors on the op amp will serve the
HI-565A also. If no op amp is used, a 0.01µF ceramic
capacitor from each supply terminal to pin 12 is sufficient,
since supply current variations are small.
The current through pin 5 is near-zero DC (Note 1); but pin
12 carries up to 1.75mA of code-dependent current from bits
1, 2, and 3. The general rule is to connect pin 5 directly to
the system “quiet” point, usually called signal or analog
ground. Connect pin 12 to the local digital or power ground.
Then, of course, a single path must connect the
analog/signal and digital/power grounds.
Current cancellation is a two step process within the
HI-565A in which code dependent variations are eliminated,
then the resulting DC current is supplied internally. First an
auxiliary 9-bit R-2R ladder is driven by the complement of
the DACs input code. Together, the main and auxiliary
ladders draw a continuous 2.25mA from the internal ground
node, regardless of input code. Part of this DC current is
supplied by the zener voltage reference, and the remainder
is sourced from the positive supply via a current mirror which
is laser trimmed for zero current through the external
terminal (pin 5).
Layout
Connections to pin 9 (IOUT) on the Hl-565A are most critical
for high speed performance. Output capacitance of the DAC
is only 20pF, so a small change or additional capacitance
may alter the op amp’s stability and affect settling time.
Connections to pin 9 should be short and few. Component
leads should be short on the side connecting to pin 9 (as for
feedback capacitor C). See the Settling Time section.
