Analog Devices Inc. LTC2063HSC6#TRPBF

Overview

LTC2063HSC6#TRPBF from Analog Devices is a single-channel, zero-drift, micropower operational amplifier in a 6-lead SC70 package, specified for –40°C to 125°C operation. It delivers 2 µA max supply current, 5 µV max input offset voltage, 0.02 µV/°C max offset drift, and rail-to-rail input/output swing across 1.7 V to 5.25 V supply - enabling precision signal conditioning in ultra-low-power gas sensors and energy-harvesting nodes.

For engineers reviewing the LTC2063HSC6#TRPBF datasheet, LTC2063HSC6#TRPBF pinout, LTC2063HSC6#TRPBF application, or LTC2063HSC6#TRPBF equivalent, key selection criteria include shutdown current (≤170 nA), EMI rejection (114 dB at 1.8 GHz), input bias current (≤100 pA over full temp range), and guaranteed performance at 125°C junction temperature.

Technical Context

The LTC2063HSC6#TRPBF employs auto-zeroing and chopper-stabilized architecture with internal 5 kHz chopping frequency to eliminate 1/f noise and minimize DC errors. Its self-calibrating circuitry achieves sub-100 nV/°C effective drift while maintaining 20 kHz gain-bandwidth product and 3.5 V/ms slew rate - suitable for DC-coupled sensor interfaces requiring long-term stability without periodic recalibration.

It integrates an on-chip EMI filter delivering 114 dB rejection at 1.8 GHz and features low-charge power-up behavior critical for duty-cycled systems. The SHDN pin operates with logic thresholds referenced to V– (V_H = 1.8 V, V_L = 0.8 V), enabling clean transition between active (1.4 µA typ) and shutdown (90 nA typ at –40°C to 85°C; 170 nA max at –40°C to 125°C) states.

FAQ

What is the maximum operating temperature specification for the LTC2063HSC6#TRPBF?

The LTC2063HSC6#TRPBF is fully specified and guaranteed over the –40°C to +125°C junction temperature range, with electrical parameters including input offset voltage drift (0.02 µV/°C max) and input bias current (100 pA max) validated across this full range. This makes the LTC2063HSC6#TRPBF suitable for under-hood automotive and industrial control applications where ambient temperatures exceed 85°C.

Does the LTC2063HSC6#TRPBF require external capacitors on its supply pins?

Yes, the LTC2063HSC6#TRPBF requires a minimum 100 nF ceramic bypass capacitor placed as close as possible between the V+ and V– pins and ground. This is essential to maintain stability, suppress supply noise, and ensure proper operation of the internal EMI filter. The datasheet specifies that inadequate bypassing may degrade PSRR and increase susceptibility to RF rectification, especially at frequencies near 1.8 GHz where EMI rejection is critical.

How does the shutdown feature of the LTC2063HSC6#TRPBF behave during power-up?

The LTC2063HSC6#TRPBF features low-charge power-up behavior: when the SHDN pin transitions from V– to V+, the amplifier enters active mode with minimal output glitch and <2 ms power-up time. This design minimizes transient injection into downstream ADCs or filters - a key advantage in duty-cycled sensor systems where the LTC2063HSC6#TRPBF is repeatedly enabled and disabled to conserve energy.

Can the LTC2063HSC6#TRPBF drive capacitive loads directly?

The LTC2063HSC6#TRPBF is stable with capacitive loads up to 100 pF when configured as a unity-gain buffer, as verified in the datasheet's small-signal response plots (Figure 2063 G55/G56). For loads exceeding 100 pF, external series resistance (≥10 Ω) or isolation via a follower stage is recommended to prevent peaking or oscillation - particularly important in PCB traces longer than 2 cm or when driving ADC input capacitance directly.

What is the significance of the 114 dB EMI rejection ratio at 1.8 GHz for the LTC2063HSC6#TRPBF?

The 114 dB EMI rejection ratio at 1.8 GHz means the LTC2063HSC6#TRPBF attenuates 100 mV_PK RF interference at that frequency to just 0.32 µV_PK at its output - effectively preventing cellular band noise from corrupting µV-level sensor signals. This on-chip EMI filter eliminates the need for external ferrite beads or LC filters in compact designs like handheld gas detectors, reducing BOM count and board area while ensuring compliance in RF-dense environments.
