The OPA170, OPA2170, and OPA4170 devices (OPAx170) are a family of 36-V, single-supply, low-noise operational amplifiers (op amps) that feature micro packages with the ability to operate on supplies ranging from 2.7 V (±1.35 V) to 36 V (±18 V). They offer good offset, drift, and bandwidth with low quiescent current. The single, dual, and quad versions all have identical specifications for maximum design flexibility.

Unlike most op amps, which are specified at only one supply voltage, the OPAx170 family of op amps is specified from 2.7 V to 36 V. Input signals beyond the supply rails do not cause phase reversal. The OPAx170 family is stable with capacitive loads up to 300 pF. The input can operate 100 mV below the negative rail and within 2 V of the positive rail for normal operation. Note that these devices can operate with full rail-to-rail input 100 mV beyond the positive rail, but with reduced performance within 2 V of the positive rail. The OPAx170 op amps are specified from –40°C to +125°C.

CIRCUIT060013 — Inverting amplifier with T-network feedback circuit

This design inverts the input signal, V_IN, and applies a signal gain of 1000 V/V or 60 dB. The inverting amplifier with T-feedback network can be used to obtain a high gain without a small value for R4 or very large values for the feedback resistors.

CIRCUIT060074 — High-side current sensing with comparator circuit

This high-side, current sensing solution uses one comparator with a rail-to-rail input common mode range to create an over-current alert (OC-Alert) signal at the comparator output (COMP OUT) if the load current rises above 1 A. The OC-Alert signal in this implementation is active low. So when the (...)
