DESCRIPTION
The LMH664X family true single supply voltage
feedback amplifiers offer high speed (130MHz), low
distortion (−62dBc), and exceptionally high output
current (approximately 75mA) at low cost and with
reduced power consumption when compared against
existing devices with similar performance.
Input common mode voltage range extends to 0.5V
below V− and 1V from V+. Output voltage range
extends to within 40mV of either supply rail, allowing
wide dynamic range especially desirable in low
voltage applications. The output stage is capable of
approximately 75mA in order to drive heavy loads.
Fast output Slew Rate (130V/µs) ensures large peakto-peak output swings can be maintained even at
higher speeds, resulting in exceptional full power
bandwidth of 40MHz with a 3V supply. These
characteristics, along with low cost, are ideal features
for a multitude of industrial and commercial
applications.
Careful attention has been paid to ensure device
stability under all operating voltages and modes. The
result is a very well behaved frequency response
characteristic (0.1dB gain flatness up the 12MHz
under 150Ω load and AV = +2) with minimal peaking
(typically 2dB maximum) for any gain setting and
under both heavy and light loads. This along with fast
settling time (68ns) and low distortion allows the
device to operate well in ADC buffer, and high
frequency filter applications as well as other
applications.
This device family offers professional quality video
performance with low DG (0.01%) and DP (0.01°)
characteristics. Differential Gain and Differential
Phase characteristics are also well maintained under
heavy loads (150Ω) and throughout the output
voltage range. The LMH664X family is offered in
single (LMH6642), dual (LMH6643), and quad
(LMH6644) options.

Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C.
Output short circuit duration is infinite for VS < 6V at room temperature and below. For VS > 6V, allowable short circuit duration is 1.5ms.
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 onto a PC board.

APPLICATION INFORMATION
CIRCUIT DESCRIPTION
The LMH664X family is based on proprietary VIP10 dielectrically isolated bipolar process.
This device family architecture features the following:
• Complimentary bipolar devices with exceptionally high ft (∼8GHz) even under low supply voltage (2.7V) and
low bias current.
• A class A-B “turn-around” stage with improved noise, offset, and reduced power dissipation compared to
similar speed devices (patent pending).
• Common Emitter push-push output stage capable of 75mA output current (at 0.5V from the supply rails) while
consuming only 2.7mA of total supply current per channel. This architecture allows output to reach within
milli-volts of either supply rail.
• Consistent performance over the entire operating supply voltage range with little variation for the most
important specifications (e.g. BW, SR, IOUT, etc.)
• Significant power saving (∼40%) compared to competitive devices on the market with similar performance.
Application Hints
This Op Amp family is a drop-in replacement for the AD805X family of high speed Op Amps in most applications.
In addition, the LMH664X will typically save about 40% on power dissipation, due to lower supply current, when
compared to competition. All AD805X family’s guaranteed parameters are included in the list of LMH664X
guaranteed specifications in order to ensure equal or better level of performance. However, as in most high
performance parts, due to subtleties of applications, it is strongly recommended that the performance of the part
to be evaluated is tested under actual operating conditions to ensure full compliance to all specifications.
With 3V supplies and a common mode input voltage range that extends 0.5V below V−, the LMH664X find
applications in low voltage/low power applications. Even with 3V supplies, the −3dB BW (@ AV = +1) is typically
115MHz with a tested limit of 80MHz. Production testing guarantees that process variations with not compromise
speed. High frequency response is exceptionally stable confining the typical −3dB BW over the industrial
temperature range to ±2.5%.
As can be seen from the typical performance plots, the LMH664X output current capability (∼75mA) is enhanced
compared to AD805X. This enhancement, increases the output load range, adding to the LMH664X’s versatility.
Because of the LMH664X’s high output current capability attention should be given to device junction
temperature in order not to exceed the Absolute Maximum Rating.
This device family was designed to avoid output phase reversal. With input overdrive, the output is kept near
supply rail (or as closed to it as mandated by the closed loop gain setting and the input voltage). See Figure 60:

However, if the input voltage range of −0.5V to 1V from V+ is exceeded by more than a diode drop, the internal
ESD protection diodes will start to conduct. The current in the diodes should be kept at or below 10mA.
Output overdrive recovery time is less than 100ns as can be seen from Figure 61 plot:

INPUT AND OUTPUT TOPOLOGY
All input / output pins are protected against excessive voltages by ESD diodes connected to V+ and V-rails (see
Figure 62). These diodes start conducting when the input / output pin voltage approaches 1Vbe beyond V+ or Vto protect against over voltage. These diodes are normally reverse biased. Further protection of the inputs is
provided by the two resistors (R in Figure 62), in conjunction with the string of anti-parallel diodes connected
between both bases of the input stage. The combination of these resistors and diodes reduces excessive
differential input voltages approaching 2Vbe. The most common situation when this occurs is when the device is
used as a comparator (or with little or no feedback) and the device inputs no longer follow each other. In such a
case, the diodes may conduct. As a consequence, input current increases and the differential input voltage is
clamped. It is important to make sure that the subsequent current flow through the device input pins does not
violate the Absolute Maximum Ratings of the device. To limit the current through this protection circuit, extra
series resistors can be placed. Together with the built-in series resistors of several hundred ohms, these external
resistors can limit the input current to a safe number (i.e. < 10mA). Be aware that these input series resistors
may impact the switching speed of the device and could slow down the device.

SINGLE SUPPLY, LOW POWER PHOTODIODE AMPLIFIER
The circuit shown in Figure 63 is used to amplify the current from a photodiode into a voltage output. In this
circuit, the emphasis is on achieving high bandwidth and the transimpedance gain setting is kept relatively low.
Because of its high slew rate limit and high speed, the LMH664X family lends itself well to such an application.
This circuit achieves approximately 1V/mA of transimpedance gain and capable of handling up to 1mApp from the
photodiode. Q1, in a common base configuration, isolates the high capacitance of the photodiode (Cd) from the
Op Amp input in order to maximize speed. Input is AC coupled through C1 to ease biasing and allow single
supply operation. With 5V single supply, the device input/output is shifted to near half supply using a voltage
divider from VCC. Note that Q1 collector does not have any voltage swing and the Miller effect is minimized. D1,
tied to Q1 base, is for temperature compensation of Q1’s bias point. Q1 collector current was set to be large
enough to handle the peak-to-peak photodiode excitation and not too large to shift the U1 output too far from
mid-supply.

SNOS966P – MAY 2001 – REVISED MARCH 2013
No matter how low an Rf is selected, there is a need for Cf in order to stabilize the circuit. The reason for this is
that the Op Amp input capacitance and Q1 equivalent collector capacitance together (CIN) will cause additional
phase shift to the signal fed back to the inverting node. Cf will function as a zero in the feedback path counteracting the effect of the CIN and acting to stabilized the circuit. By proper selection of Cf such that the Op Amp
open loop gain is equal to the inverse of the feedback factor at that frequency, the response is optimized with a
theoretical 45° phase margin.
CF =
SQRT (CIN)/(2S ˜ GBWP ˜ RF)
(1)
where GBWP is the Gain Bandwidth Product of the Op Amp
Optimized as such, the I-V converter will have a theoretical pole, fp, at:
fP = SQRT GBWP/(2SRF ˜ CIN)
(2)
With Op Amp input capacitance of 3pF and an estimate for Q1 output capacitance of about 3pF as well, CIN =
6pF. From the typical performance plots, LMH6642/6643 family GBWP is approximately 57MHz. Therefore, with
Rf = 1k, from Equation 1 and Equation 2 above.

PRINTED CIRCUIT BOARD LAYOUT AND COMPONENT VALUES SECTION
Generally, a good high frequency layout will keep power supply and ground traces away from the inverting input
and output pins. Parasitic capacitances on these nodes to ground will cause frequency response peaking and
possible circuit oscillations (see Application Note OA-15 for more information). Texas Instruments suggests the
following evaluation boards as a guide for high frequency layout and as an aid in device testing and
characterization:

Another important parameter in working with high speed/high performance amplifiers, is the component values
selection. Choosing external resistors that are large in value will effect the closed loop behavior of the stage
because of the interaction of these resistors with parasitic capacitances. These capacitors could be inherent to
the device or a by-product of the board layout and component placement. Either way, keeping the resistor values
lower, will diminish this interaction to a large extent. On the other hand, choosing very low value resistors could
load down nodes and will contribute to higher overall power dissipation.
