LT1007/LT1037
The LT1007/LT1037 achieve their low noise, in part, by
operating the input stage at 120
μ
A versus the typical 10
μ
A
of most other op amps. Voltage noise is inversely propor-
tional while current noise is directly proportional to the
square root of the input stage current. Therefore, the
LT1007/LT1037’s current noise will be relatively high. At
low frequencies, the low 1/f current noise corner fre-
quency (
≈
120Hz) minimizes current noise to some extent.
In most practical applications, however, current noise will
not limit system performance. This is illustrated in the
Total Noise vs Source Resistance plot in the Typical
Performance Characteristics section, where:
Total Noise = [(voltage noise)
2
+ (current noise R

)

Three regions can be identified as a function of source
resistance:
(i) R

(ii) 400

(iii) R

Clearly the LT1007/LT1037 should not be used in region
(iii), where total system noise is at least six times higher
than the voltage noise of the op amp, i.e., the low voltage
noise specification is completely wasted.

THE HIGH GAIN AND WIDE BANDWIDTH OF THE LT1037 (AND LT1007) IS
USEFUL IN LOW FREQUENCY, HIGH CLOSED-LOOP GAIN AMPLIFIER
APPLICATIONS. A TYPICAL PRECISION OP AMP MAY HAVE AN OPEN-LOOP
GAIN OF ONE MILLION WITH 500kHz BANDWIDTH. AS THE GAIN ERROR
PLOT SHOWS, THIS DEVICE IS CAPABLE OF 0.1% AMPLIFYING ACCURACY
UP TO 0.3Hz ONLY. EVEN INSTRUMENTATION RANGE SIGNALS CAN VARY
AT A FASTER RATE. THE LT1037’S “GAIN PRECISION-BANDWIDTH
PRODUCT” IS 200 TIMES HIGHER AS SHOWN.
