Precision specs for single-supply, high-impedance front-ends
The TLV9002QDGKRQ1: Input bias current is 5 pA typical — negligible for a 10 kΩ sensor but worth budgeting for a 1 MΩ piezoelectric or pH probe front-end where the bias current times the source impedance becomes an offset voltage. Input offset voltage is 400 µV maximum — this sets the DC accuracy floor for the signal chain; a gain of 10 multiplies it to 4 mV at the output, which is acceptable for 12-bit systems but needs calibration for 16-bit.
Package and board-fit: 8-VSSOP with 0.65 mm pitch
The TLV9002QDGKRQ1 is supplied in an 8-VSSOP package (3.00 mm width, 0.65 mm pin pitch) — the same footprint as the industry-standard 8-MSOP/TSSOP, so the PCB layout is compatible with other dual op-amps in this package family. Surface-mount assembly with Tape & Reel (TR) packaging for volume pick-and-place; Cut Tape (CT) is available for prototype or low-volume builds.
