Applications Information
Functional Description
The ISL28117, ISL28217 and ISL28417 are single, dual and
quad, low noise precision op amps. Both devices are fabricated
in a new precision 40V complementary bipolar DI process. A
super-beta NPN input stage with input bias current cancellation
provides low input bias current (180pA typical), low input offset
voltage (13V typical), low input noise voltage (8nV/
√Hz), and
low 1/f noise corner frequency (~8Hz). These amplifiers also
feature high open loop gain (18kV/mV) for excellent CMRR
(145dB) and THD+N performance (0.0005% @ 3.5VRMS, 1kHz
into 2k
Ω). A complimentary bipolar output stage enables high
capacitive load drive without external compensation.
Operating Voltage Range
The devices are designed to operate over the 4.5V (±2.25V) to
40V (±20V) range and are fully characterized at 10V (±5V) and
30V (±15V). The Power Supply Rejection Ratio typically exceeds
140dB over the full operating voltage range and 120dB
minimum over the -40°C to +125°C temperature range. The
worst case common mode input voltage range over temperature
is 2V to each rail. With ±15V supplies, CMRR performance is
typically >130dB over-temperature. The minimum CMRR
performance over the -40°C to +125°C temperature range is
>120dB for power supply voltages from ±5V (10V) to ±15V (30V).
Input Performance
The super-beta NPN input pair provides excellent frequency
response while maintaining high input precision. High NPN beta
(>1000) reduces input bias current while maintaining good
frequency response, low input bias current and low noise. Input
bias cancellation circuits provide additional bias current
reduction to <1nA, and excellent temperature stabilization.
stability at ±5V and ±15V supplies that is maintained across the
-40°C to +125°C temperature range. The low bias current TC
also produces very low input offset current TC, which reduces DC
input offset errors in precision, high impedance amplifiers.
The +25°C maximum input offset voltage (VOS) for the “B” grade is
50V and 100V for the “C” grade. Input offset voltage temperature
coefficients (VOSTC) are a maximum of ±0.6V/°C for the “B” and
gaussian-like distribution over the ±5V to ±15V supply range and over
the full temperature range. The VOS temperature behavior is smooth
temperature range.
Input ESD Diode Protection
The input terminals (IN+ and IN-) have internal ESD protection
diodes to the positive and negative supply rails, series connected
500
Ω current limiting resistors and an anti-parallel diode pair
across the inputs (Figure 54).
The series resistors limit the high feed-through currents that can
occur in pulse applications when the input dV/dT exceeds the
0.5V/s slew rate of the amplifier. Without the series resistors, the
input can forward-bias the anti-parallel diodes causing current to
flow to the output resulting in severe distortion and possible diode
failure. Figure 48 provides an example of distortion free large signal
response using a 4VP-P input pulse with an input rise time of <1ns.
The series resistors enable the input differential voltage to be equal
to the maximum power supply voltage (40V) without damage.
