The LTC6362IDD#TRPBF is a single-channel differential amplifier from Analog Devices designed to drive high-resolution SAR ADCs and condition differential signals in precision instrumentation chains. Its 45 V/µs slew rate and 180 MHz gain-bandwidth product let it settle a 10 V step to 0.01% in under 200 ns — fast enough for 16-bit SAR converters sampling at 1 MSPS without adding a separate driver buffer. The rail-to-rail differential output matches the full-scale input range of modern ADCs, preserving dynamic range without external level shifting. Supply current is 1 mA, which keeps the per-channel power budget tight in multi-channel data-acquisition systems.
34 MHz bandwidth and 75 µV offset — where the precision lives
The -3 dB bandwidth of 34 MHz defines the small-signal passband for the antialiasing filter design — a second-order Butterworth with a 3 MHz corner is a natural fit for a 1 MSPS SAR front end. Input offset voltage is 75 µV, which sets the DC error floor at about 0.001% of a 5 V full-scale range; no need for a separate autozero loop in most industrial sensor interfaces. Input bias current is 75 nA, low enough that source impedance up to 10 kΩ contributes less than 1 LSB of offset error at 16 bits.
Supply range and package — board-level fit
The 8-WFDFN package (3x3 mm) with exposed pad needs a thermal via stitch under the paddle to keep junction temperature in check at high output swing and ambient up to 85°C.
The closest functional second-source is the AD8475ARMZ-R7, which offers 50 V/µs slew rate and 150 MHz bandwidth but draws 3 mA supply current — a trade-off of higher speed for higher power. The LTC6362IDD#TRPBF's 1 mA supply makes it the lower-power pick for battery-powered or thermally constrained designs.
