LF13006/LF13007 Digital Gain Set

General Description

The LF13006 and LF13007 are precision digital gain sets

used for accurately setting non-inverting op amp gains.

Gains are set with a 3-bit digital word which can be latched

in with WR and CS pins. All digital inputs are TTL and CMOS

compatible.

The LF13006, LF13007 used in conjunction with an amplifi-

er not only satisfies the need for a digitally programmable

amplifier in microprocessor based systems, but is also use-

ful for discrete applications, eliminating the need to find

0.5% resistors in the ratio of 100 to 1 which track each

other over temperature.

The LF13006 shown below will set binary scaled gains of 1,

2, 4, 8, 16, 32, 64, and 128. The LF13007 will set gains of 1,

2, 5, 10, 20, 50, and 100 (a common attenuator sequence).

In addition, both versions have several taps and two uncom-

mitted matching resistors that allow customization of the

gain.

Features

TTL and CMOS compatible logic levels

Microprocessor compatible

Gain error 0.5% max

The gains are set with precision thin film resistors. The low

temperature coefficient of the thin film resistors and their

excellent tracking result in gain ratios which are virtually in-

dependent of temperature.

Binary or scope knob gains

Packaged in 16-pin DIP

18V
