description (continued)

The design features a 28-V/

µs minimum slew rate, which results in a high-power bandwidth. A low audio-band

noise of 28 nV/

√Hz is typical with a 55 nV/√Hz maximum at 10 Hz. Settling time to 0.1% of a 10-V step

(1-k

Ω/100-pF load) is approximately 400 ns. Gain-bandwidth product is typically 10 MHz with an 8 MHz

minimum. As such, the TLE2072 and TLE2072A offer significant speed and noise advantages at a low 1.5-mA

typical supply current per channel.

The input current characteristics traditionally associated with JFET-input amplifiers have been maintained. Input

offset voltage is graded to a 6 mV and 3.5 mV maximum for the TLE2072 and TLE2072A, respectively. Typically,

temperature coefficient of input offset voltage is 2.4

respectively. Device performance is relatively independent of supply voltage over the wide

±2.25-V to ±19-V

least 30 mA and can sustain shorts to either supply. Care must be taken to ensure that maximum power

dissipation is not exceeded.

Both the TLE2072 and TLE2072A are available in a wide variety of packages, including both the

industry-standard 8-pin small-outline version and chip form for high-density system applications. The C-suffix

devices are characterized for operation from 0

°C to 70°C, the I-suffix devices over the –40°C to 85°C range,

and the M-suffix devices over the full military temperature range of – 55

°C to 125°C.
