MOTOROLA MC14549B Successive approximation register Datasheet

SEMICONDUCTOR TECHNICAL DATA
The MC14549B and MC14559B successive approximation registers are
8–bit registers providing all the digital control and storage necessary for
successive approximation analog–to–digital conversion systems. These
parts differ in only one control input. The Master Reset (MR) on the
MC14549B is required in the cascaded mode when more than 8 bits are
desired. The Feed Forward (FF) of the MC14559B is used for register
shortening where End–of–Conversion (EOC) is required after less than eight
cycles.
Applications for the MC14549B and MC14559B include analog–to–digital
conversion, with serial and parallel outputs.

†To calculate total supply current at loads other than 50 pF:
IT(CL) = IT(50 pF) + 3.5 x 10–3 (CL = 50) VDDf
where: IT is in µA (per package), CL in pF, VDD in V, and f in kHz is input frequency.
** The formulas given are for the typical characteristics only at 25_C.
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it
is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this
high impedance circuit. For proper operation it is recommended that Vin and Vout be constrained to the range VSS (Vin or
Vout)
VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD).

OPERATING CHARACTERISTICS
Both the MC14549B and MC14559B can be operated in
either the “free run” or “strobed operation” mode for conversion schemes with any number of bits. Reliable cascading
and/or recirculating operation can be achieved if the End of
Convert (EOC) output is used as the controlling function,
since with EOC = 0 (and with SC = 1 for MC14549B but
either 1 or 0 for MC14559B) no stable state exists under continual clocked operation. The MC14559B will automatically
recirculate after EOC = 1 during externally strobed operation,
provided SC = 1.
All data and control inputs for these devices are triggered
into the circuit on the positive edge of the clock pulse.
Operation of the various terminals is as follows:
C = Clock — A positive–going transition of the Clock is
required for data on any input to be strobed into the circuit.
SC = Start Convert — A conversion sequence is initiated
on the positive–going transition of the SC input on succeeding clock cycles.
D = Data in — Data on this input (usually from a comparator in A/D applications) is also entered into the circuit on a
positive–going transition of the clock. This input is Schmitt
triggered and synchronized to allow fast response and guaranteed quality of serial and parallel data.
MR = Master Reset (MC14549B Only) — Resets all output to 0 on positive–going transitions of the clock. If removed
while SC = 0, the circuit will remain reset until SC = 1. This
allows easy cascading of circuits.
FF = Feed Forward (MC14559B Only) — Provides register shortening by removing unwanted bits from a system.
For operation with less than 8 bits, tie the output following
the least significant bit of the circuit to EOC. E.g., for a 6–bit
FROM A/D
COMPARATOR
D
C
SC
conversion, tie Q1 to FF; the part will respond as shown in
the timing diagram less two bit times. Not that Q1 and Q0 will
still operate and must be disregarded.
For 8–bit operation, FF is tied to VSS.
For applications with more than 8 but less than 16 bits, use
the basic connections shown in Figure 1. The FF input of the
MC14559B is used to shorten the setup. Tying FF directly to
the least significant bit used in the MC14559B allows EOC to
provide the cascading signal, and results in smooth transition
of serial information from the MC14559B to the MC14549B.
The Serial Out (S out) inhibit structure of the MC14559B
remains inactive one cycle after EOC goes high, while Sout of
the MC14549B remains inhibited until the second clock cycle
of its operation.
Qn = Data Outputs — After a conversion is initiated the
Q’s on succeeding cycles go high and are then conditionally
reset dependent upon the state of the D input. Once conditionally reset they remain in the proper state until the circuit is
either reset or reinitiated.
EOC = End of Convert — This output goes high on the
negative–going transition of the clock following FF = 1 (for
the MC14559B) or the conditional reset of Q0. This allows
settling of the digital circuitry prior to the End of Conversion
indication. Therefore either level or edge triggering can indicate complete conversion.
Sout = Serial Out — Transmits conversion in serial fashion. Serial data occurs during the clock period when the corresponding parallel data bit is conditionally reset. Serial Out
is inhibited on the initial period of a cycle, when the circuit is
reset, and on the second cycle after EOC goes high. This
provides efficient operation when cascaded.

TYPICAL APPLICATIONS
Externally Controlled 6–Bit ADC (Figure 2)
Continuously Cycling 12–Bit ADC (Figure 4)
Several features are shown in this application:
• Shortening of the register to six bits by feeding the seventh
output bit into the FF input.
• Continuous conversion, if a continuous signal is applied to
SC.
• Externally controlled updating (the start pulse must be
shorter than the conversion cycle).
• The EOC output indicating that the parallel data are valid
and that the serial output is complete.
Because each successive approximation register (SAR)
has a capability of handling only an eight–bit word, two must
be cascaded to make an ADC with more than eight bits.
When it is necessary to cascade two SAR’s, the second
SAR must have a stable resettable state to remain in while
awaiting a subsequent start signal. However, the first stage
must not have a stable resettable state while recycling, because during switch–on or due to outside influences, the first
stage has entered a reset state, the entire ADC will remain in
a stable non–functional condition.
This 12–bit ADC is continuously recycling. The serial as
well as the parallel outputs are updated every thirteenth
clock pulse. The EOC pulse indicates the completion of
Continuously Cycling 8–Bit ADC (Figure 3)
This ADC is running continuously because the EOC signal
is fed back to the SC input, immediately initiating a new cycle
on the next clock pulse.

Additional Motorola Parts for Successive
Approximation ADC
Externally Controlled 12–Bit ADC (Figure 5)
Monolithic digital–to–analog converters — The
MC1408/1508 converter has eight–bit resolution and is available with 6, 7, and 8–bit accuracy. The amplifier–comparator block — The MC1407/1507 contains a high speed
operational amplifier and a high speed comparator with adjustable window.
With these two linear parts it is possible to construct SA–
ADCs with an accuracy of up to eight bits, using as the register one MC14549B or one MC14559B. An additional CMOS
block will be necessary to generate the clock frequency.
Additional information on successive approximation ADC
is found in Motorola Application Note AN–716.
In this circuit the external pulse starts the first SAR and
simultaneously resets the cascaded second SAR. When Q4
of the first SAR goes high, the second SAR starts conversion, and the first one stops conversion. EOC indicates that
the parallel data are valid and that the serial output is complete. Updating the output data is started with every external
control pulse.
