UCSP, Micropower, Single-Supply, 10V,

Rail-to-Rail I/O Op Amps

1) The on-board charge pumps generate a small

amount of 700kHz switching noise at the op amp’s

output. The amplitude of this noise is typically

100µVP-P. The noise is not referred to the input, and

is independent of amplifier gain. The charge-pump

switching frequency is well beyond the amplifier’s

200kHz bandwidth, and is therefore unnoticeable in

most applications.

2) The charge pumps typically require up to 20µs on

power-up to fully energize the internal supply rails

(Figure 3).

Power Supplies and Layout

The MAX4162/MAX4163/MAX4164 are guaranteed to

operate from a single 2.5V to 10.0V power supply, but

full rail-to-rail operation typically extends below 2V. For

single-supply operation, bypass the power supply with a

1µF capacitor in parallel with a 0.1µF ceramic capacitor.

If operating from dual supplies, bypass each supply to

ground.

Good layout improves performance by decreasing the

amount of stray capacitance at the op amp’s inputs and

output. To decrease stray capacitance, minimize both

trace and external component lead lengths, and place

external components close to the op amp’s pins.

UCSP Package Consideration

For general UCSP package information and PC layout

considerations, please refer to the Maxim Application

Note (Wafer-Level Ultra-Chip-Board-Scale-Package).

UCSP Reliability

The UCSP represents a unique packaging form factor

that may not perform equally to a packaged product

through traditional mechanical reliability tests. UCSP

reliability is integrally linked to the user’s assembly

methods, circuit board material, and usage environ-

ment. The user should closely review these areas when

considering use of a UCSP. Performance through oper-

ating life test and moisture resistance remains uncom-

promised as it is primarily determined by the

wafer-fabrication process. Mechanical stress perfor-

mance is a greater consideration for a UCSP package.

UCSPs are attached through direct solder contact to

the user’s PC board, foregoing the inherent stress relief

of a packaged product lead frame. Solder joint contact

integrity must be considered.

Table 1 shows the testing done to characterize the

UCSP reliability performance. In conclusion, the UCSP

is capable of performing reliably through environmental

stresses as indicated by the results in the table.

Additional usage data and recommendations are

detailed in the UCSP application note, which can be

found on Maxim’s website at www.maxim-ic.com.
