Lower Power Op Amp: Low Noise Reference,
Utility Sine Wave
Design Note 1042
Catherine Chang, Philip Karantzalis and Aaron Schultz
Introduction
Our op amp family has expanded with industryleading speed versus supply current. The LTC В®6258/
LTC6259/LTC6260 family (single, dual, quad) provides 1.3MHz at a super low 20ВµA supply current,
with 400ВµV maximum offset voltage and rail-to-rail
input and output. In combination with a 1.8V to 5.25V
supply, this op amp enables countless applications
requiring uncompromised performance with low
power and low voltage at reasonable cost. FigureВ 1 shows such a configuration. First, a very low
cutoff frequency follows the LT6656 output (RIN1 and
CIN1, lower than 5Hz cutoff). Large values of RIN1 can
develop significant offset voltage due to the LTC6258вЂ™s
input bias current. Setting RIN1 to 2.7kО© produces
an offset that is lower than the nominal input offset
voltage of the op amp. CIN1 can be larger or smaller,
with more or less filtering accordingly. The voltage
withstanding requirement of CIN1 is low, resulting in
relatively large capacitance in a small volume. Low Noise Reference
The LT6656 is a precision series voltage reference
with a low 1ВµA supply current. In combination with …

Utility Sine Wave
One does not expect to generate a sine wave with
вЂ“100dBc distortion using a 5V low power op amp. All
the same, a bandpass filter using the LTC6258 can
combine with an easy-to-use low power oscillator
to create a sine wave at low cost, low voltage and
extremely low dissipation.
Active Filter
The bandpass filter of FigureВ 1 is AC coupled to an
input. As a result, the LTC6258 input does not place a
burden on the previous stage to develop a particular
absolute common mode voltage. A simple resistor divider with RA1 and RA2 provides biasing for the …

Low Power Op Amps: Only 20ВµA for 1.3MHz,
240ВµA for 30MHz
Aaron Schultz, Catherine Chang and Philip Karantzalis Our op amp family has expanded with industry-leading speed versus supply current.
For super low 20ВµA supply current, the LTC6258/LTC6259/LTC6260 (single, dual,
quad) provide 1.3MHz at a with 400ВµV maximum offset voltage and rail-to-rail
input and output. The still-low 240ВµA of the LTC6261/LTC6262/ LTC6263 (single,
dual, quad) provide 30MHz with 400ВµV maximum offset voltage and rail-to-rail
input and output. In combination with 1.8V to 5.25V supply, these op amps enable
applications requiring good performance with low power and low voltage.
LOW NOISE REFERENCE This circuit takes advantage of the ability
of the LTC6258 to drive large capacitive
loads. Use of a large output capacitor
bank attached to the LTC6258 enables
significant bypassing of follow-on circuits
that use the reference voltage. In total, 12 | July 2017 : LT Journal of Analog Innovation LT6656
