2 14-Lead Ceramic Dual In-Line Package [CERDIP] and 14-Lead Plastic Dual In-Line Package [PDIP] Figure 2. 16-Lead Standard Small Outline Package [SOIC_W] GENERAL DESCRIPTION The op400 is the first monolithic quad Operational amplifier that features OP77-type performance. Precision performance is not sacrificed with the op400 to obtain the space and cost savings offered by quad amplifiers. The op400 features an extremely low input offset voltage of less than 150 V with a drift of less than V/ C, guaranteed over the full military temperature range. Open-loop gain of the op400 is more than 5 million into a 10 k load, input bias current is less than 3 nA, common-mode rejection (CMR) is more than 120 dB, and Power supply rejection ratio (PSRR) is less than V/V. On-chip Zener zap trimming achieves the low input offset voltage of the op400 and eliminates the need for offset nulling.

3 The op400 conforms to the industry-standard quad pinout, which does not have null terminals. The op400 features low Power consumption, drawing less than 725 A per amplifier . The total current drawn by this quad amplifier is less than that of a single OP07, yet the op400 offers significant improvements over this industry-standard op amp. Voltage noise density of the op400 is a low 11 nV/ Hz at 10 Hz, half that of most competitive devices . The op400 is an ideal choice for applications requiring multiple precision Operational amplifiers and where low Power consumption is critical.
