Product Description
The CMV1016 is a high performance CMOS operational amplifier available in a small SOT23-6 package.
Operating with very low supply current, it is ideal for
battery operated applications where power, space and
weight are critical.
Performance is similar to CAMD’s CMV1010 SOT
Amp, with the addition of a shutdown pin to greatly
reduce supply current when idle. The shutdown mode
is controlled by an extra pin, and is compatible with
most logic family signal levels.
Ideal for use in personal electronics such as cellular
handsets, pagers, cordless telephones and other
products with limited space and battery power.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating conditions indicate ratings
for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and
the test conditions, see the Electrical Operating Characteristics.
Note 2: Human Body Model, 1.5KΩ in series with 100pF.
Note 3 : Applies to both single-supply and split-supply operation. Continuous short ckt operation at elevated ambient temperatures can
result in exceeding the maximum allowed junction temperature of 150°C.
Note 4 : The maximum power dissipation is a function of TJ (MAX), θJA and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (TJ (MAX) - TA)/θJA . All numbers apply for packages soldered directly to a PC board.

temperature rise are small, a short analysis is worth
investigating.
Applications Information
1. Input Common Mode Range and Output
Voltage Considerations
The CMV1016 is capable of accommodating an input
common mode voltage equal to one volt below the
positive rail and all the way to the negative rail. It is
also capable of output voltages equal to both power
supply rails. Voltages that exceed the supply voltages
will not cause phase inversion of the output, however,
ESD diode clamps are provided at the inputs that can
be damaged if static currents in excess of ±5mA are
allowed to flow in them. This can occur when the
magnitude of input voltage exceeds the rail by more
than 0.3 volt. To preclude damage, an applications
resistor, RS, in series with the input is recommended
as illustrated in Figure 1 whose value for RS is given
by:
VIN – (V+ + 0.3V)
RS > —————————
5mA
Obviously, the worst case from a power dissipation
point of view is when the output is shorted to either
ground in a single rail application or to the opposite
supply voltage in split rail applications. Since device
only draws 60µA supply current (100µA maximum), its
contribution to the junction temperature, TJ, is negligible. As an example, let us analyze a situation in
which the CMV1016 is operated from a 5 volt supply
and ground, the output is “programmed” to positive
saturation, and the output pin is indefinitely shorted to
ground. In general:
PDISS = (V+ – VOUT)*IOUT + IS*V+
Where: PDISS = Power dissipated by the chip
V+ = Supply voltage
VOUT = The output voltage
IS = Supply Current
For V+ (or V-) equal to 2.2 volts and VIN equal to 10
volts, Rs should be chosen for a value of 2.5 KΩ or
greater.
The Shutdown pin also provides ESD clamp diodes
that will be damaged if the signal exceeds the rail by
0.3 volts and should also be limited to <5mA by
inserting the appropriate resistor between the input
signal or logic gate and the Shutdown input.
The contribution to power dissipation due to supply
current is 500µW and is indeed negligible as stated
above.
The primary contribution to power dissipation occurs in
the output stage. V+ – VOUT would equal 5V – 0V = 5V
while the short circuit current would be 25mA. The
power dissipation would be equal to 125mW.
TJ = TA + θJA* PDISS
Where: TA = The ambient temperature
θJA = The thermal impedance of the package
junction to ambient
The SOT23 exhibits a θJA equal to 325°C/W. Thus for
our example the junction rise would be about 41°C
which is clearly not a destructive situation even under
an ambient temperature of 85°C.
3. Input Impedance Considerations
Figure 1.
2. Output Current and Power Dissipation
Considerations
The CMV1016 is capable of sinking and sourcing
output currents in excess of 7mA (V+ = 2.2 volts) at
voltages very nearly equal to the rails. As such, it
does not have any internal short circuit protection
(which would in any event detract from its rail to rail
capability). Although the power dissipation and junction
The CMV1016 exhibits an input impedance typically in
excess of 1 Tera Ω (1 X 1012 ohms) making it very
appropriate for applications involving high source
impedance such as photodiodes and high output
impedance transducers or long time constant integrators. High source impedances usually dictate large
feedback resistors. But, the output capacitance of the
source in parallel with the input capacitance of the
CMV1016 (which is typically 3pF) create a parasitic
pole with the feedback resistor which erodes the
phase margin of the amplifier. The usual fix is to
bypass, RF, as shown in Figure 2 with a small capacitor to cancel the input pole. The usual formula for
calculating CF always results in a value larger than that
is required:

5. Power Supply Decoupling
Since the parasitic capacitance can change between
the breadboard and the production printed circuit
board, we favor the use of a "gimmick", a technique
perfected by TV technicians in the 1950’s. A gimmick
is made by taking two lengths (typically about a foot)
of small gauge wire such as AWG 24, twisting them
together, and then after baring all ends soldering the
gimmick across RF. With the circuit operating, CF is
"adjusted" by clipping short lengths of the gimmick off
until the compensation is nominal. Then simply
remove the gimmick, take it to an impedance bridge,
and select the capacitor accordingly.
The CMV1016 is not prone to oscillation without the
use of power supply decoupling capacitors, however to
minimize hum and noise pick-up, it is recommended
that the rails be bypassed with 0.01µF capacitors.
6. Turn On and Turn Off (Shut Down)
Characteristics
The turn off delay (Disable Response), tOFF, is defined
as the time between the shut down signal crossing the
disable threshold (typically V+ – 1 volt) and the time
for the amplifier’s output to come within 10% of zero. It
is largely governed by a propagation delay within the
CMV1016 of few hundred nanoseconds followed by an
exponential decay determined by the load resistance
in parallel with the load capacitance.
The turn on delay (Enable Response), tON, is defined
as the time between the shutdown signal crossing the
threshold and the time the output reaches to within
10% of its final value. tON is largely independent of
supply voltage and input level.
7. Typical Applications
Figure 2.
4. Capacitive Load Considerations
The CMV1016 is capable of driving capacitate loads in
excess of 100pF without oscillation. However, significant peaking will result. Probably the easiest way
minimize this problem is to use an isolation resistor as
shown in Figure 3.
Illustrated in Figure 4 is a Sample and Hold Amplifier
capable of operating from a single rail, but it will work
equally well with split rails The circuit will accommodate input voltages (common mode) from zero volts to
V+ – 1 volt. The Shut Down feature of the CMV1016 is
used to disable A1 whose output acts like a very high
impedance in this mode. The high slew rate of the
CMV1016 and large output current minimize
Acquisition Time. A2 presents a very high input
impedance and very low bias current. A Logic "1", a
voltage > V+ – 1 volt will put the circuit into "Sample"
mode. A Logic “0” will put the circuit in "Hold" mode.
For the values shown, Acquisition Time to 0.1% is
typically 10µs for a zero to 4 volt input, the hold step
is typically 400µV, and the droop rate at 85°C is
0.1µV/µs. Overall accuracy is better than 0.01%. For
minimum droop, C1 should be of polystyrene
construction.

CMV1016
CALIFORNIA MICRO DEVICES
The circuit illustrated in Figure 5 provides a simple
analog switch capable of operating from supply
voltages as low as 2.2 volts. The circuit takes advantage of the CMV1016’s shutdown feature which places
the output stage in a high impedance mode. The
outputs are simply "wire OR’d", and as configured, a
Logic "1" (Logic In voltage > V+ – 1 volt), VIN2 is
selected.
