Low Power Op Amp: Low Power Filter, Headphone
DriverВ Revisited
Design Note 1041
by Aaron Schultz
Introduction
A new family of op amps features industry leading
speed versus supply current. The LTC6261/LTC6262/
LTC6263 family (single, dual, quad) provides 30MHz
at a low 240ВµA supply current, 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 uncompromised
performance with low power and low voltage.
Active Filters
This new set of op amps with high MHz-to-mA ratios
provides an opportunity to look at filter circuits in a
new light. The two filter examples discussed here
display performance previously unachievable with
such low power.
Second Order Bessel Filter
Ample bandwidth and low supply current enable
deployment of active filters in portable and other low
L, LT, LTC, LTM, Linear Technology and the Linear logo are registered …

100mW delivered to reach 110dBSPL. With 32О©, the
RMS current is 56mA and voltage 1.8V; with 120О©,
29mA and 3.5V. Introduction
A new family of op amps features industry leading
speed versus supply current. The LTC6261/LTC6262/
LTC6263 family (single, dual, quad) provides 30MHz
at a low 240ВµA supply current, 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 uncompromised
performance with low power and low voltage. Given a 3.3V supply and the output of one LTC6261
amplifier, there may not be sufficient drive capability to yield 100mW. However, the combination of
two 180В° phased amplifiers is enough to provide
the necessary drive to reach upwards of 100mW
delivered power. Duplication of this bridge drive
circuit enables power to both left and right sides. Bridge-Tied Differential Output Amplifier
The low supply current at the bandwidth and noise
performance allows for excellent fidelity at a fraction
of the usual dissipation in portable audio equipment. …

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
