Description

The THAT 300, 320 and 340 are large

geometry, 4-transistor, monolithic NPN and/or PNP

arrays. They exhibit both high speed and low noise,

with excellent parameter matching between transis-

tors of the same gender. Typical base-spreading

resistance is 25

Ω

for the PNP devices (30

Ω

for the

low-gain NPNs), so their resulting voltage noise is

under 1 nV/√Hz. This makes the 300 series ideally

suited for low-noise amplifier input stages, log ampli-

fiers, and many other applications. The four-NPN

transistor array is available in versions selected for

with minimums of 150 (300A) or 300 (300B).

Fabricated in a dielectrically isolated, comple-

mentary bipolar process, each transistor is electri-

cally insulated from the others by a layer of

insulating oxide (not the reverse-biased PN junctions

used in conventional arrays). As a result, they exhibit

inter-device crosstalk and DC isolation similar to

that of discrete transistors. The resulting low

collector-to-substrate capacitance produces a typical

NPN f

of 350 MHz (325 MHz for the PNPs).

Substrate biasing is not required for normal opera-

tion, though the substrate should be ac-grounded to

optimize speed and minimize crosstalk.

An eight-transistor bare-die array with similar

performance characteristics (the THAT 380G) is also

available from THAT Corporation. Please contact us

directly or through your local distributor for more

information. Military-grade temperature range

packages are available from TT Semiconductor (see

www.ttsemiconductor.com for more information).
