AEC-Q100 dual op amp in a hermetic ceramic flatpack
It delivers a gain-bandwidth product of 5.3 MHz with a supply current of just 100 µA per channel, making it a fit for always-on sensor conditioning in battery-backed or thermally harsh environments. The rail-to-rail output stage allows direct interface to ADCs or comparators without a second supply rail.
The 0.02 V/µs slew rate is the headline limitation on this part. At full 10 V output swing, the maximum undistorted frequency is roughly 300 Hz. For a 1 V peak-to-peak signal, that extends to about 3 kHz. This is not a part for audio line drivers, fast ADC buffers, or any waveform requiring more than a few kilohertz of small-signal bandwidth. Where it works is DC-accurate amplification, thermocouple conditioning, strain-gauge bridges, and any low-frequency loop where the 5.3 MHz GBW is used for DC gain, not AC bandwidth.
100 µA per channel — the battery-life enabler
At 100 µA per channel quiescent, the TLV2422MUB draws 200 µA total for both amplifiers. In a 24/7 sensor node powered by a 500 mAh primary cell, that alone accounts for about 4 mA·h per day — leaving most of the budget for the MCU and radio. The 1 pA input bias current (typical) also means the external resistor divider or photodiode bias network does not need to fight a DC error term. For always-on automotive cabin sensors or remote industrial transmitters, this quiescent number is the selection gate.
Hermetic 10-CFP — procurement implications
The 10-CDFF / 10-CFP is a ceramic dual flatpack with gold-plated leads, not a plastic SOIC or TSSOP. This package is standard for high-reliability programs that require hermeticity — MIL-STD-883 screening, space-level lot acceptance, or long-life sealed modules. The surface-mount footprint is non-standard compared to JEDEC plastic packages; verify the land pattern against the package drawing before committing the PCB. Sourcing is through independent distribution channels that handle ceramic and hi-rel inventory; this is not a part stocked in high volume at general-purpose distributors.
