Philips Semiconductors Linear Products
10-Bit high-speed multiplying D/A converter
Product specification
MC3410,
MC3410C
DESCRIPTION
The MC3410 series are 10-bit Multiplying Digital-to-Analog
Converters. They are capable of high-speed performance, and are
used as general-purpose building blocks in cost-effective D/A
systems.
The Philips Semiconductors design provides complete 10-bit
accuracy without laser trimming, and guaranteed monotonicity over
temperature. Segmented current sources, in conjunction with an
R-2R DAC provides the binary weighted currents. The output buffer
amplifier and voltage reference have been omitted to allow greater
speed, lower cost, and maximum user flexibility.
FEATURES
• 10-bit resolution and accuracy (±0.05%)
• Guaranteed monotonicity over temperature
• Fast settling time—250ns typical
• Digital inputs are TTL and CMOS compatible
• Wide output voltage compliance range
• High-speed multiplying input slew rate—20mA/µs
• Reference amplifier internally-compensated
• Standard supply voltages +5V and -15V
APPLICATIONS
• Successive approximation A/D converters
• High-speed, automatic test equipment
• High-speed modems
• Waveform generators
• CRT displays
• Strip CHART and X-Y plotters
• Programmable power supplies
• Programmable gain and attenuation

Product specification
MC3410,
MC3410C
When a DC reference voltage is used, capacitive bypass to ground
is recommended. The 5V logic supply is not recommended as a
reference voltage. If a well regulated 5.0V supply, which drives logic,
is to be used as the reference, R16 should be decoupled by
connecting it to the +5.0V logic supply through another resistor and
bypassing the junction of the two resistors with a 0.1µF capacitor to
ground.
The reference amplifier is internally-compensated with a 10pF
feed-forward capacitor, which gives it its high slew rate and fast
settling time. Proper phase margin is maintained with all possible
values of R16 and reference voltages which supply 2.0mA reference
current into Pin 16. The reference current can also be supplied by a
high impedance current source of 2.0mA. As R16 increases, the
bandwidth of the amplifier decreases slightly and settling time
increases. For a current source with a dynamic output impedance of
1.0MΩ, the bandwidth of the reference amplifier is approximately
half what it is in the case of R16=1.0kΩ, and settling time is ≈ 10µs.
The reference amplifier phase margin decreases as the current
source value decreases in the case of a current source reference,
so that the minimum reference current supplied from a current
source is 0.5mA for stability.

OUTPUT VOLTAGE COMPLIANCE
The output voltage compliance ranges from -2.5 to +0.2V. As shown
in Figure 2, this compliance range is nearly constant over
temperature. At the temperature extremes, however, the compliance
voltage may be reduced if VEE>-15V.
ACCURACY
Absolute accuracy is a measure of each output current level with
respect to its intended value. It is dependent upon relative accuracy
and full-scale current drift. Relative accuracy, or linearity, is the
measure of each output current with respect to its intended fraction
of the full-scale current. The relative accuracy of the MC3410 is
fairly constant over temperature due to the excellent temperature
tracking, of the implanted resistors. The full-scale current from the
reference amplifier may drift with temperature causing a change in
the absolute accuracy. However, the MC3410 has a low full-scale
current drift with temperature.
The MC3410 are accurate to within ±0.05% at 25°C with a reference
current of 2.0mA on Pin 16.
