DESCRIPTION

The OPA2613 offers very low 1.8nV√Hz input noise in a

wideband, unity-gain stable, voltage-feedback

architecture. Intended for xDSL driver applications, the

OPA2613 also supports this low input noise with

exceptionally low harmonic distortion, particularly in

differential configurations. Adequate output current is

provided to drive the potentially heavy load of a

twisted-pair line. Harmonic distortion for a 2V

differential

output operating from +5V to +12V supplies is ≤ −95dBc

through 1MHz input frequencies. Operating on a low

6.0mA/ch supply current, the OPA2613 can satisfy most

xDSL driver requirements over a wide range of possible

supply voltagefrom a single +5V condition, to ±5V, on up

to a single +12V design.

General-purpose applications on a single +5V supply will

benefit from the high input and output voltage swing

available on this reduced supply voltage. Low-cost

precision integrators for PLLs will also benefit from the low

voltage noise and offset voltage. Baseband I/Q receiver

channels can achieve almost perfect channel match with

noise and distortion to support signals through 5MHz with

> 14-bit dynamic range.

Requiring only 6mA/ch quiescent current, the OPA2613 swings to within 1.0V of either supply rail and delivers in excess of 280mA at room temperature.

The dual OPA2613 is configured as a differential gain stage to provide signal drive to the primary of the transformer (here, a step-up transformer with a turns ratio of 1:2). The main advantage of this configuration is the cancellation of all even harmonic distortion products.

"#$% www.ti.com SBOS249H − JUNE 2003 − REVISED AUGUST 2008 With the previous information available, it is now possible to select a supply voltage and the turns ratio desired for the transformer as well as calculate the headroom for the OPA2613. The model (shown in Figure 8) can be described with the following set of equations: 1. First, as available output swing: V PP + VCC * (V1 ) V2) * I P 2.

"#$% www.ti.com SBOS249H − JUNE 2003 − REVISED AUGUST 2008 OUTPUT CURRENT AND VOLTAGE The OPA2613 provides output voltage and current capabilities that are unsurpassed in a low-cost dual monolithic op amp. Under no-load conditions at 25°C, the output voltage typically swings closer than 1V to either supply rail; tested at +25°C, swing limit is within 1.1V of either rail. Into a 12Ω load (the minimum tested load), it delivers more than ±280mA continuous output current.

Figure 14 shows the op amp noise model for the differential configuration. IN Evaluating these equations for the OPA2613 ADSL circuit and component values of Figure 6 gives a total output spot noise voltage of 23.3nV/√Hz and a total equivalent input spot noise voltage of 3.2nV/√Hz.

Under this condition, PDL = VS2/(4 × RL) where RL includes feedback network loading. Note that it is the power in the output stage and not into the load that determines internal power dissipation.

"#$% www.ti.com SBOS249H − JUNE 2003 − REVISED AUGUST 2008 This total effective impedance should be set to match the trace impedance. The high output voltage and current capability of the OPA2613 allows multiple destination devices to be handled as separate transmission lines, each with their own series and shunt terminations. If the 6dB attenuation of a doubly-terminated transmission line is unacceptable, a long trace can be series-terminated at the source end only.
