JFET quad op-amp for precision analog signal chains
The Texas Instruments TL034CPWR is a JFET-input quad operational amplifier in a 14-TSSOP package, designed for applications requiring high input impedance, low bias current, and moderate speed.
Supply current and power budget across four channels
Total supply current is 870 µA for all four amplifiers — roughly 217 µA per channel. On a ±15 V rail that's about 13 mW total quiescent dissipation, which keeps the 14-TSSOP package cool even in a densely populated board. The 40 mA output current per channel gives enough drive for ADC inputs, reference buffers, or modest cable loads without an external buffer stage.
The 10 V to 30 V supply span covers standard industrial rails: ±5 V, ±12 V, ±15 V, or single-ended 12 V and 24 V. No extra regulator is needed if your system already runs a ±15 V analog supply. For outdoor or under-hood use you would need the industrial-grade variant (TL034B or similar, if available).
Package and footprint — 14-TSSOP
The TL034CPWR comes in a 14-TSSOP (0.173", 4.40 mm width) body, surface-mount only. The fine-pitch TSSOP footprint requires careful solder-paste stencil design; the 0.65 mm lead pitch is standard for this package family.
Lifecycle and compliance
The ROHS3 compliance covers the current exemption set, suitable for EU and global markets.
