The TLE207x series of JFET-input operational amplifiers more than double the bandwidth and triple the slew rate of the TL07x and TL08x families of BiFET operational amplifiers. Texas Instruments Excalibur process yields a typical noise floor of 11.6 nV/√Hz, 17-nV/√Hz ensured maximum, offering immediate improvement in noise-sensitive circuits designed using the TL07x. The TLE207x also has wider supply voltage rails, increasing the dynamic signal range for BiFET circuits to ±19 V. On-chip zener trimming of offset voltage yields precision grades for greater accuracy in dc-coupled applications. The TLE207x are pin-compatible with lower performance BiFET operational amplifiers for ease in improving performance in existing designs. BiFET operational amplifiers offer the inherently higher input impedance of the JFET-input transistors, without sacrificing the output drive associated with bipolar amplifiers. This makes them better suited for interfacing with high-impedance sensors or very low-power loads.
The TLE207x family of JFET‑input operational amplifiers offers low noise, high speed, and wide supply‑voltage rails. Compared with the earlier TLO7x and TLO8x families, the TLE207x series provides more than double the bandwidth and three times the slew rate, with a typical noise floor of 11.6 nV/√Hz.
The datasheet lists multiple package options (small ceramic, plastic DIP, flat‑pack, etc.) for each device variant, provides absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics such as input offset voltage, bias current, and output swing. Mechanical dimensions and an important notice on warranty and product availability are also included.
