ADA4092-4

The ADA4092-4 features a unique input stage that allows the input voltage to exceed either supply safely without any phase reversal or latch-up; this is called overvoltage protection (OVP). The ADA4092-4 is specified over the extended industrial temperature range of ?40°C to +125°C. The ADA4092-4 is part of the growing selection of 36 V, low power op amps from Analog Devices, Inc., see Table 1. The ADA4092-4 is available in the 14-lead TSSOP surface-mount package. The ADA4092-4 quad is a micropower, single-supply, 1.4 MHz bandwidth amplifier featuring rail-to-rail inputs and outputs. It is guaranteed to operate from a +2.7 V to +30 V single supply as well as from ±1.35 V to ±15 V dual supplies. Applications for these amplifiers include portable telecommunications equipment, power supply control and protection, and interface for transducers with wide output ranges. Sensors requiring a rail-to-rail input amplifier include Hall effect, piezoelectric, and resistive transducers. The ability to swing rail-to-rail at both the input and output enables designers, for example, to build multistage filters in single-supply systems and to maintain high signal-to-noise ratios (SNR).

The features of ADA4092-4 can be summarized as (1)single-supply operation: 2.7 V to 36 V; (2)wide input voltage range; (3)rail-to-rail output swing; (4)low supply current: 200 A/amplifier; (5)wide bandwidth: 1.4 MHz; (6)high phase margin: 69°; (7)slew rate: 0.4 V/s; (8)low offset voltage: 1.50 mV maximum; (9)no phase reversal; (10)overvoltage protection (OVP): 25 V above/below supply rails at ±5 V/ 12 V above/below supply rails at ±15 V.

The absolute maximum ratings of ADA4092-4 are (1)supply voltage: 36 V; (2)input voltage: refer to the input overvoltage protection section; (3)differential input voltage: ±V SY; (4)input current: ±5 mA; (5)output short-circuit duration to GND: Indefinite; (6)storage temperature range: -65°C to +150°C; (7)operating temperature range -40°C to +125°C; (8)junction temperature range: -65°C to +150°C; (9)lead temperature (soldering, 60 sec): 300°C.
