SGM8051/2/4 250MHz, Rail-to-Rail Output

SGM8053/5 CMOS Operational Amplifier

PRODUCT DESCRIPTION

The SGM8051/3(single),SGM8052/5(dual),SGM8054

(quad) are rail-to-rail output voltage feedback amplifiers

offering ea of u and low cost. They have bandwidth

and slew rate typically found in current feedback

amplifiers. All have a wide input common-mode voltage

range and output voltage swing, making them easy to

u on single supplies as low as 2.5 V.

Despite being low cost, the SGM8051 ries provide

excellent overall performance. They offer wide

bandwidth to 250 MHz (G

=+1) along with 0.1 dB flatness

out to 37 MHz（G = +2）and offer a typical low power of

2.3 mA/amplifier.

The SGM8051 ries is low distortion and fast ttling

make it ideal for buffering high speed A/D or D/A

converters. The SGM8053/5 has a power-down disable

feature that reduces the supply current to 75

µA. The

features make the SGM8053/5 ideal for portable and

battery-powered applications where size and power are

critical. All are specified over the extended –

40°C to

+125°C temperature range.

NOTES

1. Stress above tho listed under Absolute Maximum Ratings may cau permanent damage to the device. This is a stress

rating only; functional operation of the device at the or any other conditions above tho indicated in the operational

ction of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may

affect device reliability.

CAUTION

This integrated circuit can be damaged by ESD.

Shengbang Micro-electronics recommends that all

integrated circuits be handled with appropriate

precautions. Failure to obrve proper handling and

installation procedures can cau damage.

ESD damage can range from subtle performance

degradation to complete device failure. Precision

integrated circuits may be more susceptible to

damage becau very small parametric changes

could cau the device not to meet its published

10µF

10µF

0.1µF

The SGM805x family is optimized for bandwidth and speed,

not for driving capacitive loads. Output capacitance will

create a pole in the amplifier’s feedback path, leading to

excessive peaking and potential oscillation. If dealing with

load capacitance is a requirement of the application, the two

strategies to consider are (1) using a small resistor in ries

with the amplifier’s output and the load capacitance and (2)

reducing the bandwidth of the amplifier’s feedback loop by

increasing the overall noi gain.

Figure 1 shows a unity gain follower using the ries resistor

strategy. The resistor isolates the output from the capacitance

and, more importantly, creates a zero in the feedback path

that compensates for the pole created by the output

capacitance.

. Series Resistor Isolating Capacitive Load

A ground plane layer is important for high speed circuit

design. The length of the current path speed currents in an

inductive ground return will create an unwanted voltage

noi. Broad ground plane areas will reduce the parasitic

inductance.

Power-Supply Bypassing and Layout

Input-to-Output Coupling

The SGM805x family operates from either a single +2.7V to

+5.5V supply or dual ±1.35V to ±2.75V supplies. For

single-supply operation, bypass the power supply V with a

DD

0.1µF ceramic capacitor which should be placed clo to the

V pin. For dual-supply operation, both the V and the V

DDDDSS

supplies should be bypasd to ground with parate 0.1µF

ceramic capacitors. 2.2µF tantalum capacitor can be added

for better performance.

Good PC board layout techniques optimize performance by

decreasing the amount of stray capacitance at the op amp’s

inputs and output. To decrea stray capacitance, minimize

trace lengths and widths by placing external components as

clo to the device as possible. U surface-mount

components whenever possible.

For the high speed operational amplifier, soldering the part to

the board directly is strongly recommended. Try to keep the

high frequency big current loop area small to minimize the

EMI (electromagnetic interfacing).

To minimize capacitive coupling, the input and output signal

traces should not be parallel. This helps reduce unwanted

positive feedback.
