LTC2058
36V, Low Noise Zero-Drift
Operational Amplifier
DESCRIPTION
The
LTC
®
2058
is a dual, low noise, zero-drift operational
amplifier that offers precision DC performance over a
wide supply range of 4.75V to 36V. Offset voltage and 1/f
noise are suppressed, allowing this amplifier to achieve
a maximum offset voltage of 5μV and a DC to 10Hz input
noise voltage of 200nV
P-P
(Typ). The LTC2058’s self-
calibrating circuitry results in low offset voltage drift with
temperature, 0.025μV/°C (Max), and practically zero drift
over time. The amplifier also features an excellent power
supply rejection ratio (PSRR) of 150dB and a common
mode rejection ratio (CMRR) of 150dB (Typ).
The LTC2058 provides rail-to-rail output swing and an
input common mode range that includes the V
–
rail. In
addition to low offset and noise, this amplifier features
a 2.5MHz (Typ) gain-bandwidth product and a 1.6V/μs
(Typ) slew rate.
Wide supply range, combined with low noise, low offset,
and excellent PSRR and CMRR make the LTC2058 well
suited for high dynamic-range test, measurement, and
instrumentation systems.

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
The LTC2058I is guaranteed to meet specified performance
from –40°C to 85°C. The LTC2058H is guaranteed to meet specified
performance from –40°C to 125°C.
Note 3:
These parameters are guaranteed by design. Thermocouple effects
preclude measurements of these voltage levels during automated testing.
V
OS
is measured to a limit determined by test equipment capability.
Note 4:
These specifications are limited by automated test system
capability. Leakage currents and thermocouple effects reduce test
accuracy. For tighter guaranteed specifications, please contact LTC
Marketing.
Note 5:
Input BIAS current is measured using an equivalent source
impedance of 100MΩ || 51pF.
Note 6:
Minimum specifications for these parameters are limited by
the capabilities of the automated test system, which has an accuracy of
approximately 10µV for V
OS
measurements. For reference, 30V/1µV is
150dB of voltage ratio.
Note 7:
MSE package only.
